Patent ID: 6855625

Claim:
A manufacturing method of a multilayer substrate, which is made of laminated films and has electrodes formed at each of two principle surfaces, wherein the method comprises: laminating single-sided conductor patterned films, each of which has a resin film and a conductor pattern, which is formed only on a single side of the resin film, to form a lamination, wherein the single-sided conductor patterned films include a first single-sided conductor patterned film, and the lamination is arranged such that the resin film of the first single-sided conductor patterned film forms an outermost surface of the laminated films and the conductor pattern of the first single-sided conductor patterned film is formed on an inner side of the resin film of the first single-sided conductor patterned film; and forming an opening in the resin film of the first single-sided conductor patterned film, so that one of the electrodes of the multilayer substrate is formed by the conductor pattern of the first resin film.
