PROBLEM TO BE SOLVED: To provide a manufacturing method where an interlayer insulating resin and the barrier metal of a plated wiring uppermost layer can obtain high adhesiveness, for a method for obtaining the adhesiveness between a fine wiring surface and the interlayer insulating resin especially in the wiring transfer method of a multilayer interconnection board. SOLUTION: The manufacturing method of the multilayer interconnection board should comprise a process for forming a light-sensitive resist film on one surface of a substrate made of a conductive material that can be etched, a process for exposing the light-sensitive resist film for development, and a process for making coarse the surface of the substrate where the light-sensitive resist film is removed by the process. |
