摘要： A three-dimensional wiring board comprises a metal base having a roughed surface, a heat-bonding type of polyimide film without using adhesive, bonded to the roughed surface and serving as an electric insulating layer, and a copper foil for a conductive layer, bonded to the other surface of the polyimide film. A method for manufacturing the wiring board comprises a roughing treatment process for plating or oxidizing the surface of a metal base, thereby forming a roughed surface, a contact bonding process for attaching a polyimide film to the roughed surface and a copper foil by thermocompression bonding, thereby forming a laminate material, a patterning process for etching the copper foil into a desired conductive pattern, and a bending process for bending the laminate material into a desired three-dimensional shape by press working.
