To obtain an electroplated layer which has high durability and the peeling of which hardly occurs by roughening the surface of a synthetic rubber or synthetic resin through machining of the surface into an uneven surface, forming an electrically conductive coating film on the roughened surface and performing electroplating onto the conductive coating film.
In this method, the surface of a synthetic rubber or synthetic resin is roughened and a conductive coating film is formed on the roughened surface and electroplating is performed onto the conductive coating film. At the time of roughening the surface of a synthetic rubber or synthetic resin, the surface is subjected to machining into an uneven surface. This machining into an uneven surface is performed preferably by using an abrasive blasting method that comprises allowing a projected material to impact on the surface of an object. Thus, the uneven surface which has about 30 to 50μm surface roughness and a high anchoring effect can be formed. Also, the conductive coating film can be formed by coating the roughened surface with a coating material contg. a metal powder and an organic solvent.
