Summary:PURPOSE:To reduce the man-hour in the manufacture of a material for the frame of spectacles, to facilitate its working, to uniformize the thickness of noble metal, to increase the thickness as well and to manufacture the material for the frame of spectacles, furthermore light in weight, and excellent in properties such as color, corrosion resistance and strength. CONSTITUTION:Parts for the frame of spectacles are worked by a material easy to dissolve by chemicals, and after that, its outer surface or the outer surface of a round wire or a deformed wire worked immediately before the working of the parts used for the frame of spectacles is coated with noble metal by an electric casting method, and its core material is thereafter dissolved by chemicals to manufacture the hollow material for the frame of spectacles made of noble metal.
