To enable a magnetic body to be adhered in a stable condition to the skin without using an adhesive to improve convenience by attaching a rubber coating onto at least one face of core materials comprising plate-formed magnetic bodies.

This magnetic health device is constituted of a plurality of core materials of ferrite magnet in a plate shape of length and width about 3 cm and thickness about 2 mm and a coating layer 3 to cover at least one face of the core materials 2. The core materials 2 are housed in a core material containing part with a plurality of spaces formed almost matching to the size of the core material 2 and orderly placed so that each overlapped part is the same polarity to prevent neighboring core materials 2 from attracting and superposing each other. A material containing wild silk thread in a sheet formed of silicone rubber is preferably used as the coating layer 3.
