金属部品の組立品にも抗菌性が求められている。2. Description of the Related Art In recent years, as the trend toward hygiene and cleanliness has increased, it has been required to impart antibacterial properties to all products. For example, eyeglass frames, watch bands, pedestal rings, necklaces, bracelets, earrings, etc. Many metal parts are also required to have antibacterial properties.

品の組立品は非常に高価なものになり、実用化の妨げに
なっている。In such a method of forming an antibacterial layer before assembling a metal component, an antibacterial property is imparted to each minute metal component,
Since it is assembled into a metal part assembly, the working efficiency is very poor, and as a result, the antimicrobial metal part assembly is very expensive, which hinders practical use.

う問題点があった。[Problems] However, in the above-mentioned method, since the metal parts are assembled in such a manner that minute metal parts are densely assembled, for example, the complicated shape parts 1a, 1a of the eyeglass frame 1 shown in FIG. 1b, the gap 2a of the watch band 2 shown in FIG. 2, and the complex shaped portion 3a of the base ring 3 shown in FIG. Since the antibacterial layer cannot be formed, the required antibacterial effect cannot be exerted, and the manufacturing apparatus is complicated and expensive.

うちに消失するところもあるという問題点があった。In the method of (1), an antibacterial layer is also formed on a gap between metal parts or a portion having a complicated shape in an assembly. However, since the antibacterial layer is formed on the surface of the metal part, the surface property is reduced. For example, there is a problem that it affects the surface color and the like, and also, depending on the material of the antibacterial layer, the antibacterial layer is worn out due to abrasion and the like, and the antibacterial effect may be lost in a relatively short time. There was a point.
