ELASTIC MATERIAL-CONTAINING SPHERE AND METHOD OF MANUFACTURING CHAIN USING ELASTIC MATERIAL-CONTAINING SPHERE

PROBLEM TO BE SOLVED: To simplify a manufacturing method by manufacturing spheres in a state where an elastic material is contained from the first in a chain using elastic material-containing spheres and a method of manufacturing the chain. SOLUTION: The method for manufacturing an ornament is characterized in that after a large number of continuous spheres are formed of a metal pipe in which a rubber of an elastic resin solid or hollow pipe-shaped cord-like body is inserted, through-holes are formed in the elastic material in the pipe at narrowed parts after or before the continuous spheres are separated from each other at the narrowed parts, and a chain, a cord body, or a wire is passed through the through-holes.
