PURPOSE: To enhance releasability and abrasion resistance by allowing a hard conductive film and a fluoroplastic film to coexist on the surface of a base metal in a flush state.

CONSTITUTION: A hard conductive film 2 and a fluoroplastic film 3 are allowed to coexist on the surface of a base metal 1 in a flush state. As the base metal, steel, stainless steel, copper or a copper alloy, aluminum or an aluminum alloy or the like can be used and the hard conductive film 2 is formed, for example, using a metal metal carbide, metal boride, metal nitride or an alloy thereof and pref. exposed to the surface of the base metal 1. The fluoroplastic film 3 is formed using a tetrafluoroethylene resin or a tetrafluoroethylene/ perfluoroalkoxy resin. By this method, a composite metallization having good releasability and high surface abrasion resistance and capable of preventing the charge of static electricity can be obtained.
