Abstract:
A multilayer wiring board assembly laminated with a plurality of multilayer wiring board assembly components, the multilayer wiring board assembly being manufactured by a method comprising:preparing the plurality of multilayer wiring board assembly components, wherein each of the plurality of multilayer wiring board assembly components comprises: a resin film having properties of adhesivity, a copper foil bonded to one surface of the resin film, a through hole opened through the copper foil and the resin film, and a conductive paste embedded by screen printing in the through hole from a side of the copper foil such that a leading edge of the conductive paste is projected from the resin film; and laminating the multilayer wiring board assembly components with other multilayer wiring board assembly components such that the leading edge of the conductive paste is pressed against at least one of the conductive paste and the copper foil of an adjacent one of the multilayer wiring board assembly components, wherein the leading edge of the conductive paste is in close contact with at least one of the conductive paste and the copper foil of the adjacent one of the multilayer wiring board assembly components such that an electric connection having electric conductivity is formed.
