Abstract
A plating layer (or vapor deposition layer) which exhibits a metallic color is formed on the surface of a molded resin part. A color film with transmittance which is molded and which has a desired color for design is formed on the surface of the above plating layer (or vapor deposition layer). This color film comprises moldable materials such as resin including, for example, polymer compounds such as PET, PC, urethane or combinations of these. Thereby, a press button switch can be gained which imparts a feeling of high quality through a metallic finish design, of which the degree of design freedom is high and which can prevent color unevenness of the key top from occurring.
