ABSTRACT:
An aromatic polyimide film having a metallic surface comprises a substrate film of an aromatic polyimide containing essentially no inorganic particle, an aromatic polyimide resin layer containing non-conductive metal oxide particles dispersed therein and a metal layer, superposed in order. A portion of the non-conductive metal oxide particles located in the vicinity of the surface of the aromatic polyimide resin layer is reduced into metal so that the surface of the resin layer is made electroconductive.
