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

即ち、Ｈｄ＝Ｎ（Ｉ／μ0 ）で表せる。但し，Ｎ；反磁

上述した反磁界係数（Ｎ）は、磁石のＮ極とＳ極間の距

しまう。In the 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 ). However, N: demagnetizing factor, μ 0 : magnetic permeability of vacuum, I: strength of magnetization.
The above-mentioned diamagnetic field coefficient (N) has a large value when the distance between the N pole and the S pole of the magnet is small, and the strength of magnetization becomes weak.

ているためでもある。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. However, in the printing method described above,
The thickness of the thick film magnet is generally 0.2 μm to 0.3 μm or less. This is because if the thickness is 1 mm or more in printing, burrs are generated on the edges during printing, and the appearance is deteriorated. Further, this is also because when the thickness is increased, a stress is applied to the magnet (magnetic substance), and the magnet is easily peeled off from the substrate.

A predetermined number of grooves having a depth of about 1 mm are formed at predetermined intervals. An example of a silicon rubber substrate provided with this groove is shown in FIG. Figure 7
2A is a side view and FIG. 2B is a top view. In FIG. 1, 1 is a silicon rubber substrate, and 2 is a groove arranged in the silicon rubber substrate 1. Then, in this groove 2, a magnetic material powder, for example, an average particle size 2 having a basic composition of (SmCo 5 ) 2

An appropriate amount of carbitol as a solvent is added to the thermosetting silicone resin, and this is sufficiently mixed with, for example, a three-roll mill to prepare a magnetic paste, and the magnetic paste is filled in the groove 2.

Thereafter, the magnetic composition thermally cured in step 5 is magnetized with a magnetizer to form a magnet. For example, a silicon rubber substrate on which a magnetic composition is formed is placed on a magnetizing machine in which an N pole is formed on one surface and an S pole is formed on the other surface, and magnetic force lines pass through in the thickness direction, and magnetized at 15,000 o'clock. , And a magnetic effect element (magnet).

Specifically, each magnet portion of the silicon substrate having a plurality of magnets embedded therein is separated by cutting or punching for each magnet as shown in FIG. The separating shape is, for example, a circular silicon rubber substrate in which a columnar magnet is embedded. Each of the magnet parts separated in this way has an adhesive bond on the magnet-embedded surface or on a surface opposite to the magnet-embedded surface, on which an adhesive agent having a size sufficient to fix the magnet part to the skin or the like is applied. Paste it on. FIG. 10 shows a state in which the magnet portion is attached to the adhesive bond. Figure 10

じ、工程が複雑になるなどの欠点を有していた。However, in the method of manufacturing the magnet portion by the conventional printing method, the thickness of the magnet portion is 0.2 μm to 0.3 μm as described above, and there is no influence of the demagnetizing field. Cannot obtain a strong magnetic force. Further, in the method of forming the groove and forming the magnetic body therein, the thickness of the magnet portion can be set to 1 mm or more by a simple method such as printing. However, when it is attached to an adhesive bond on the opposite side of the surface where the magnet is embedded, to the surface of the magnet, the magnetic material comes into direct contact with the skin. Therefore, there is a big restriction on the material of the magnetic body, and in the case of a material which is not desired to be directly touched with the skin, it is necessary to cover the upper portion of the magnetic body with a thin printing such as silicone, and the process becomes complicated.

てしまう。Further, when an adhesive having a size large enough to fix the magnet portion to the skin or the like is applied to the magnet embedding surface, there is a problem in strength, and the thickness of the top substrate cannot be made too thin. When the groove is formed on the silicon rubber substrate, the thickness needs to be about 0.3 mm or more. For this reason,
The magnetic force that reaches the skin is weakened, and at a thickness of about 0.3 mm, it is weakened by about 20% as compared with the case of directly contacting the skin.
