PROBLEM TO BE SOLVED: To provide a magnetic necklace including permanent magnetic bodies suppressing the fracture thereof. SOLUTION: The magnetic necklace 1 has a number of substantially elliptical capsules 3 and a number of substantially spherical capsules 5. The capsules 3 and the capsules 5 are alternately connected with connection rods 7. Some of the capsules 3 house the permanent magnetic bodies 9 each having a columnar body formed with radiused surfaces 9d along the rims. Thus, the rims of the permanent magnetic body 9 are blunted and the fracture is suppressed. COPYRIGHT: (C)2005,JPO&NCIPI
