METHOD FOR FORMING METALLIC LAYER

摘要

PROBLEM TO BE SOLVED: To form a metallic layer which covers the inside of a defective hole, has a uniform thickness, and has a superior surface quality. SOLUTION: This forming method comprises the step of forming a metallic undercoating 4 on the surface of a plastic film 1 with a dry electroplating method; and the step of forming an electroconductive organic polymer coating selectively inside the defective hole 6 to cover it, by contacting an organic monomer-containing liquid with the metallic undercoating 4: and further comprises forming a plated metallic film 10 on the metallic undercoating 4 with a wet process, by forming the metallic film with an electroplating method.
