<p>PROBLEM TO BE SOLVED: To provide a health promoting instrument capable of applying an effect over a wide range without ruggedness as a whole. SOLUTION: A sheet-like rubber magnet 11 is formed by mixing and molding SmFeN rare earth magnetic materials of fine grains composed of a grain diameter of <=5μm and rubber resin. The magnetic characteristics of this rubber magnet become satisfactory rather than a ferrite magnet conventionally used for such a health promoting instrument. Therefore, when this rubber magnet is attached on the center of a main body 10 of belt, a lumbago band, with which a magnetic force effect is exerted over a wide range, can be formed.</p> |
