Provided is a metal substrate having high adhesion strength and stability between a metal film and a plastic film, and at the same time, allowing a thin film thickness of the metal film.n n n The plastic film serving as a base is placed in a silane coupling agent coating apparatus and dried at a temperature of 300 ° C., and then the vaporized silane coupling agent is plasticized while maintaining the temperature at 300 ° C. It is sprayed on a film, and a silane coupling agent is coated on the surface of the plastic film, and copper is formed on the surface of the plastic film coated with the coupling agent by sputtering, and the copper sputtering film is provided. On the plastic film, the plating method is plated with a glossy copper clad film having a desired film thickness.n n n n Metal layer, plastic film, silane coupling agent, coating, carbon |
