PURPOSE:To enable increase of the area of a curing portion, by a method wherein a core in a U-shape in cross section is formed in an annular shape, and a conductive wire is wound around the groove of the cross section to form an electromagnet. CONSTITUTION:A curing part 1 has a core 7 formed such that a member in a U-shape in cross section is formed in an annular shape with arms 5 and 5, located vertically in parallel to each other, and a bottom part 6. A conductive wire 8 is wound around a groove formed with the arms 5 and 5 and the bottom part 6 of the core 7, and is covered with a plastic case 9. Four granular permanent magnets 10, namely two magnets are mounted in positions situated facing each other on the surface of the upper arm 5 of the core 7. Thus, The position, to which the magnet 10 is secured, of case 9 is expanded. A thermostat 11 is mounted in an arbitrary spot on the outside of the portion around which the conductive wire 8 is wound. Since the curing part 1 is formed in an annular shape, a magnetic flux can pass, for example, a neck and a shoulder through a head, and an arm and a foot can be inserted in the ring to cure these spots. |
