N polarity appears in the upper half of the surface and S polarity appears in the lower half. For this reason, the elongated filamentous medium entity 1 is virtually magnetized in an arbitrary cross section of the elongated filamentous medium entity 1 as shown in FIG. The direction of magnetization is shown in FIG. 5 (c) so as not to change in the length direction, but the direction of the magnetic field lines coming out of the N pole is the length direction of the elongated filamentary entity 1; For example, they may be in different directions such as staggered, spiral, or randomly changing, and a change can be made to increase the magnetic effect.

  As the strength of magnetization, in this embodiment, the magnetic flux density on the surface of the elongated filamentary solid body 1 is 40 to 70 millitesla. From the mixing ratio of the ferrite and rubber, appropriate flexibility can be obtained, so that it can be easily worn on the body, and the magnetic flux density can be increased within an appropriate range, so that the health promotion effect is high.

  In addition, in the following embodiment, although the cross section of the elongate filament solid substance 1 is circular, it is not limited to this, Other shapes, such as an ellipse, a square, and a hexagon, may be sufficient. Moreover, coloring and a pattern may be attached | subjected to the surface of the elongate filament solid substance 1 according to liking, and a design is not limited by this.
