られている。2. Description of the Related Art Conventionally, a thick-film magnet or a plastic magnet is disposed on the front surface, and a non-magnetic substrate (sheet) coated with an adhesive is adhered on the back surface to an affected part to treat shoulder stiffness and recover muscle fatigue. Magnetic therapy devices for such purposes are often used. In order to efficiently form this thick film magnet on a substrate, a method is used in which a ferromagnetic material paste containing a thermosetting resin or the like is printed on a substrate by a method such as printing and then heated and cured to be magnetized.

る。In a magnet used in such a magnetic therapy device, the demagnetizing field (Hd) can be expressed by the following equation.
That is, it can be expressed by Hd = N (I / μ 0 ). Here, N: demagnetizing coefficient, μ 0 : magnetic permeability in vacuum, I: intensity of magnetization.
The demagnetizing coefficient (N) described above becomes a large value when the distance between the N pole and the S pole of the magnet is small, and the magnetization intensity is weakened. Therefore, in order to make the strength of the magnetic force close to 1000 Gauss, it is necessary to make the thickness 1 mm or more.

易くなるという欠点を有しているためでもある。However, in the above-described printing method, the thickness of the thick film magnet is 0.2 μm.
In general, it is about 0.3 μm or less. This is because if the thickness is 1 mm or more by printing, burrs are formed on the edges during printing, and the appearance is deteriorated. Furthermore, when the thickness is increased, a stress is applied to the magnet (magnetic substance), and the magnet (magnetic substance) has a disadvantage that it is easily peeled off from the substrate.

In the second embodiment, as shown in FIG. 6A, a silicon rubber substrate 11 having the same thickness as the desired thickness of the magnet (for example, about 1 mm) is formed on the silicon rubber substrate 11 having the same shape as the groove of the first embodiment. For example, a through hole 12 having a diameter of about 6 mm is formed. The through hole 12 may be formed by punching the silicon rubber substrate 11 into a groove shape by a method such as pressing. This punching operation is much simpler than the grooving operation, and a large number of through-holes (for example, several or several tens) can be made at one time at a time, greatly improving the work efficiency. Can be. And a silicon rubber substrate 15 having no through hole 12 formed therein,
The silicon rubber substrate 11 with the opening is fixed by bonding with an adhesive or the like, and as a result, a silicon rubber substrate having the same grooves as in the first embodiment is manufactured.

を参照して以下に説明する。Third Embodiment In each of the above embodiments, a magnetic paste made of a ferromagnetic powder and a thermosetting resin is prepared and filled into a groove having a depth of about 1 mm by a printing method to form a magnet. It was about an example to do. However, the present invention is not limited to the above example. For example, a through hole for forming a magnet similar to that of the second embodiment is formed in a silicon rubber substrate, and only a ferromagnetic powder or a ferromagnetic material is formed therein. The amount of the ferromagnetic material may be increased and the coercive force may be increased by pouring a powder obtained by adding an appropriate amount of carbitol as a solvent to the powder and sealing the mixture. FIG. 7 shows a third embodiment according to the present invention configured as described above.
This will be described below with reference to FIG.

Then, as in FIG. 6, a through hole 12 having a diameter of, for example, about 6 mm is formed in the substrate. Then, for example, a substrate 21 having approximately half the thickness (0.5 mm in the third embodiment) of the substrate 15 of the second embodiment is adhered to one surface of the substrate 11 with an adhesive or the like.

Then, a substrate 22 having a thickness of about 0.5 mm similar to the other surface is adhered and fixed to the other surface of the substrate 11 with an adhesive or the like. Then, this is subjected to a magnetizing step similar to step 5 in FIG. 1 and an adhesive bond adding step of step 6 to obtain a magnetic therapy device.

Reference numeral 25 in FIG. 7 denotes a magnet formed of substantially ferromagnetic powder alone. In the third embodiment, since the density of the magnetic substance was increased, a value close to about 200 Gauss was obtained with a Gauss meter.

供できる。As described above, the thick-film magnet manufactured in the above-described process is very resistant to aging, and can be easily formed in a desired shape at a desired position on the substrate 2 in a desired shape. Moreover, the surface is covered with a silicone resin harmless to the human body. For this reason, even if it is brought into direct contact with the skin of a human body, it does not cause metal allergy or the like. By applying the present invention to a magnetic therapy device, it is possible to obtain a very inexpensive and highly stable magnetic therapy device. Further, by forming a plurality of magnets and arranging the magnets at a position corresponding to a pot of a human body, it is possible to provide a magnetic treatment device having a high therapeutic effect.
