PURPOSE:To enhance a therapeutic effect by forming a plurality of recesses at an axial interval at a predetermined pitch, inverting polarities axially alternately to form poles in the recesses, and differentiating polarities of the poles on opposed surfaces to the recesses, and mounting particular magnets. CONSTITUTION:A soft linear magnet 1 is formed of a stripelike linear magnet 2 made of plastic magnet and particular magnets 3 of ferrite or rare earth element. Recesses 21 are formed at a predetermined pitch (t) on a surface of the magnet 2, so inverted that adjacent recesses are different polarities to form the poles in a vertical direction. The magnets 3 are formed in a rectangular parallelepiped shape bent upward at upper surfaces with substantially the same flat surface shape in such a manner that the poles of the upper surface become N- and S-poles. The magnets 3 are so engaged with the recesses 21 that the pole polarities of opposed surfaces are different, and fixed with adhesive. Thus, maximum magnetic flux density of the poles are increased to improve therapeutic effect. |
