を同時に達成することができる。The thick film magnet of the present embodiment manufactured as described above has a surface magnetic flux of approximately 700 gauss as measured by a Gauss meter. The thick film magnet separately manufactured in this manner has a very good adhesion to the substrate. For example, in the case of the above-described thick film magnet having the second mixing ratio, the substrate is substantially peeled off when the substrate is bent by 180 degrees. Although there were many problems in practice, the use of the two-layer thick-film magnet described above improves the adhesion to the substrate and the magnetic characteristics without any separation even when the substrate is bent at 180 degrees. Can be achieved at the same time.

Although the example in which the magnetic pastes are mixed together in the step 1 has been described, the present embodiment is not limited to the above example. In the step 1, only the first magnetic paste is mixed and the step 3 is completed. The second magnetic paste may be mixed later.
Alternatively, it is needless to say that mixing may be performed between step 2 and step 3 or completely separately.

上に複数の磁石を配設した例を図５に示す。As described above, according to this embodiment, when a ferromagnetic material is printed on a silicon rubber substrate that is harmless to the human body, a paste is formed by using a silicon thermosetting resin as a vehicle, and furthermore, an adhesive portion with the substrate is formed. In, the ratio of the resin common to the substrate is increased, so that very good adhesion can be maintained. Further, since the ratio of the ferromagnetic material powder is increased, a magnet having good magnetic properties can be obtained. In this example, in addition to using the silicon rubber substrate as the substrate, by using a silicon resin harmless to the human body as a vehicle, the adhesion to the silicon rubber substrate is increased, and the safety as a magnetic effect element is improved. Comfort is also improved. Therefore, even if the skin is in contact with the skin for a long time, it can be used safely without causing allergies. For this reason, the above-mentioned thick film magnet is incorporated as a magnetic therapy device utilizing a magnetic effect, and it is possible to provide a highly safe magnetic therapy device that can be used with confidence by bringing the magnet into close contact with an affected part.

Further, the configuration of the ferromagnetic material forming the thick film is not limited to the above example, for example, as a ferromagnetic material powder,
The same effect can be achieved by using a ferromagnetic material powder having a basic composition of Sm-Co instead of Nd-Fe-B.
