<P>PROBLEM TO BE SOLVED: To provide a tourmaline filled tube which is of help in maintaining, restoring and promoting a physical condition by efficiently performing an electrical action. <P>SOLUTION: The tourmaline filled tube 100 is an endless tube which seals a tourmaline powder and which is made of a flexible material. A plurality of rugged parts are provided on the inner peripheral wall of the tube. That is, the tube 100 increases a frictional opportunity of the powder as the surface area of the inside of the tube is increased, and its electrical action is more strongly performed. Since the tube is formed in a ring state of the flexible material, the tube can be worn on the body without causing a load on the neck, the waist, the wrist, the ankle or the like. The tube is deformed to meet the movement of the body, and hence the above-mentioned frictional opportunity is further increased, and the electrical action is synergistically strengthened. <P>COPYRIGHT: (C)2004,JPO |
