    • PROBLEM TO BE SOLVED: To provide a manufacturing method for a ring which effectively manufactures the ring with a high yield, in which the design of the ring more strongly recalls a concept that the ring has been manufactured of one and the same material.SOLUTION: A ring 2 for men and a ring 3 for women are obtained by separating one material. A convex part 2a and a convex part 2b which are projected from the outer peripheral surface of the ring generated by separation are formed on the ring 2 for men, and a convex part 3a and a convex part 3b, which are projected from the outer peripheral surface of the ring generated by the separation are formed on the ring 3 for women. Thus, an appearance image that the convex part 2a and the convex part 3a, and the convex part 2b and the convex part 3b are obtained by separation and manufactured of one and the same material is given to the ring 2 for men and the ring 3 for women.
    • 要解决的问题:提供一种以高产率有效地制造环的环的制造方法,其中环的设计更强烈地回忆出环已经由同一材料制造的概念。解决方案: 通过分离一种材料获得男性戒指2和女士戒指3。 从男子的环2上形成有从分离产生的环的外周面突出的凸部2a和凸部2b,以及从外周突出的凸部3a和凸部3b 通过分离产生的环的表面形成在妇女的环3上。 因此,通过分离并制造同一材料得到凸部2a和凸部3a以及凸部2b和凸部3b的外观图像被赋予男士用环2和环3 女用。
