Abstract

PROBLEM TO BE SOLVED: To make a magnetic force act on the finger in spite of being a decorative ring and to improve blood circulation by placing a long magnetic body on a ring along the circumferential direction and covering the circumference with a thick decorative metal to form the ring part and then magnetizing the long magnetic body. SOLUTION: As the decorative metal 23 with a prescribed thickness, not only a noble metal such as gold, silver, white gold, platinum, and alloys of those metals, but also red brass are included. A long magnetic body 22 is placed on the center and the circumference is bent into a ring shape with a prescribed diameter using a core bar 24 etc. At that time, it is preferable to form slopes 25, which becomes longer toward the outer periphery side, on the both side faces of the long material 21 in a sheath and core structure. The long material 21 in the sheath and core structure is bent to make the slopes 25 mutually abut on and the both ends are connected to form the material into a ring with a prescribed diameter.
