PROBLEM TO BE SOLVED: To provide a composite endless annular resin film formed of a laminate of a resin film and a metallic thin film, which has improved adhesion between the metallic thin film and the resin film.SOLUTION: An endless annular resin film contains a filler predominantly in the outside surface. The filler is detached so that irregularities are formed on the outside surface of the endless annular resin film. A metallic thin film is laminated on the surface having irregularities, so that the adhesion between the metallic thin film and the endless annular resin film is remarkably improved. |
