The jewelry piece includes the elongated body that includes a tube formed by a flexible material, multiple magnet pieces that are inserted into the inside of the tube over the entire length of the tube other than both end sections of the tube, and caps that close both ends of the tube, and the ornament attachment member that the elongated body passes through, and that is retained due to the magnetic attraction force exerted by a magnetic substance at a prescribed position in the longitudinal direction of the elongated body. The ornament attachment member is formed by a core body made of a magnetic material, through which the elongated body passes, and by an ornament that is integrally formed with the core body so as to surround the core body.
