As described above, the second substrate is arranged between the first substrate and the third substrate, and the outer peripheral portion of the first substrate and the outer peripheral portion of the third substrate are coupled by spacers around the second substrate. Therefore, it is necessary to make the projected area of the first substrate and the third substrate in the thickness direction larger than the projected area of the second substrate in the thickness direction. This hinders the miniaturization of the non-contact communication module.

The present invention is to reduce the size of a non-contact communication module and an electronic device.

In order to solve the above problems, the non-contact communication module according to one aspect of the present invention includes a first substrate, a second substrate, a first antenna, a connection portion, and a housing .

One of the guide portion of the housing and the guide portion of the second substrate is a guide convex portion, and the other is a guide concave portion into which the guide convex portion is movably inserted along the first direction.

The non-contact communication module of such an aspect can be miniaturized. This is because the projected area of the second substrate is smaller than the projected area of the first substrate, and the second substrate is arranged so that the projected area is within the projected area of the first substrate. By setting the area to at least the minimum size in which the first antenna can be provided, the projected area of both the first substrate and the second substrate can be reduced. As a result, the non-contact communication module can be miniaturized.
Further, the fixing portion can be fixed to the first substrate without the fixing portion interfering with the second substrate. By inserting the guide convex portion into the guide concave portion and moving the second substrate in the first direction, the second substrate can be easily arranged in the housing portion of the housing.

The module M1 as described above exhibits the following technical features and effects.
Technical features and effects 1)
The projected area of the first substrate 100a and the second substrate 200a of the module M1 in the ZZ'direction can be reduced, and as a result, the size of the module M1 can be reduced. The reason is as follows.
When at least one first antenna 500a and at least one second antenna 700a are provided on the first surface 101a of the first substrate 100a, as described above, the projected area of the first substrate 100a is at least one first. The size may be the minimum at which the antenna 500a and at least one second antenna 700a can be provided. On the other hand, the projected area of the second substrate 200a is smaller than the projected area of the first substrate 100a, and is arranged within the projected area of the first substrate 100a. Therefore, the projected area of the first substrate 100a and the second substrate 200a is within the projected area of the first substrate 100a. Moreover, at least one first circuit unit 600a is mounted on the second surface 102a of the first substrate 100a, and at least one second circuit unit 800a is formed on the first surface 201a and the second surface 202a of the second substrate 200a. Since it is mounted on at least one surface and both circuit units are distributed and arranged, it is not necessary to increase the projected area of the first substrate 100a in order to secure the mounting areas of both circuit units. From the above, since the projected area of both substrates in the ZZ'direction is reduced, the projected area of the module M1 in the ZZ' direction can be reduced accordingly. When the connecting portion 300a is arranged between the first substrate 100a and the second substrate 200a within the projected area of the second substrate 200a, it is outside the range of the projected area of the second substrate 200a of the connecting portion 300a. As a result, the projected area of the module M1 in the ZZ'direction can be reduced as compared with the case where the module M1 is arranged in.
When the second antenna 700a is not provided on the first surface 101a of the first substrate 100a, as described above, the projected area of the first substrate 100a is the minimum size at which at least one first antenna 500a can be provided. Can be. Also in this case, the projected area of the first substrate 100a and the second substrate 200a is within the projected area of the first substrate 100a. Since at least one first circuit unit 600a can be mounted on the second surface 102a of the first substrate 100a, the first surface 201a of the second substrate 200a, and / or the second surface 202a of the second substrate 200a, at least one of them can be mounted. It is not necessary to increase the projected area of the first substrate 100a in order to secure the mounting area of one first circuit unit 600a. Also in this case, since the projected area of both substrates in the ZZ'direction is reduced, the projected area of the module M1 in the ZZ' direction can be reduced accordingly.

Technical features and effects 2)
When the connecting portion 300a electrically and mechanically connects the first substrate 100a and the second substrate 200a, the first substrate 100a and the second substrate 200a can be easily attached to the housing 400a as follows. Can be done.
Since the second substrate 200a is electrically and mechanically connected to the first substrate 100a as described above, the first substrate 100a is inserted into the accommodating portion 420a of the housing 400a from the Z direction side. By fixing the fixing portion 110a of the outer peripheral portion to at least one fixing portion 410a located outside the range of the projected area of the second substrate 200a from the Z direction side, both the first substrate 100a and the second substrate 200a are once fixed. Is fixed to the housing 400a.
Moreover, when the housing 400a has at least one guide portion 430a, at least one guide portion 210a of the second substrate 200a is guided by at least one guide portion 430a of the housing 400a to the second substrate 200a. At least one fixing portion 110a of the mechanically connected first substrate 100a is aligned with at least one fixing portion 410a of the housing 400a. Therefore, it becomes easy to fix at least one fixing portion 110a to at least one fixing portion 410a.
Further, when at least one fixing portion 410a is provided on the edge portion, flange, convex portion of the housing 400a or the contact surface of at least one guide portion 430a, the fixing portion 110a on the outer peripheral portion of the first substrate 100a is provided. Is fixed to at least one fixing portion 410a, and the outer peripheral portion of the first substrate 100a comes into contact with the contact surface. As a result, both the first substrate 100a and the second substrate 200a are positioned in the housing 400a at the same time. The same applies when the connecting portion 300a electrically connects the first substrate 100a and the second substrate 200a, and another connecting portion electrically connects the first substrate 100a and the second substrate 200a. It has the technical features and effects of.

Technical features and effects 3)
When at least one first circuit unit 600a is mounted on the second surface 102a of the first substrate 100a, the distance between at least one first circuit unit 600a and at least one first antenna 500a becomes close, and between them. Since the electrical length of the above is shortened, the signal loss generated between at least one first circuit unit 600a and at least one first antenna 500a is reduced, and the loss due to signal reflection and the jitter due to noise are increased.
