Abstract:
To provide a metal twisted wire that can develop in rich variations with a rope style used as a basis, and can be applied not only to an eyeglass frame but also to accessories and the like.SOLUTION: In a metal twisted wire formed by twisting a plurality of metal wires, the plurality of metal wires are separated into at least one first metal wire 11 and another second metal wire 12. The first metal wire 11 and the second metal wire 12 are formed of metal wires different in properties. By twisting the first metal wire 11 and the second metal wire 12, a form is made such that while the first metal wire 11 and the second metal wire 12 are mutually twisted, the second metal wire 12 or the first metal wire 11 wounds around the first metal wire 11 or the second metal wire 12 in an ivy-like way. A difference in the property may be a diameter, cross-sectional shape, rigidity and degree of elongation of the metal wire, or a combination of two or more of the diameter, cross-sectional shape, rigidity and degree of elongation thereof.SELECTED DRAWING: Figure 1
