PROBLEM TO BE SOLVED: To form a highly adhesive film on a metal foil in a method of forming a film on a metal foil. SOLUTION: A plurality of island-shaped structures 12 are formed on the surface 10a of the metal foil 10 while partly exposing the surface. Then, a film 20 is formed to cover these island-shaped structures. These island-shaped structures form irregularity on the surface of the metal foil. Once the film 20 is formed to cover the island-shaped structures, the irregularity consisting of the island-shaped structures and the film are meshed with each other. This raises adhesiveness of the film with respect to the metal foil. COPYRIGHT: (C)2007,JPO&INPIT
