Abstract
Abstract A coaxial conductor interconnection wiring board includes at least one coaxial conductor and at least one conductive hole having an inner wall covered with a metal film connected to a central signal conductor of the coaxial conductor. The conductive shield of the coaxial conductor is connected to the ground layer by connection metal layers. A conductor insulating layer surrounds the metallized conductor hole and the connection metal layers surround a part of the additional conductor insulating layer. Thus, the conductive hole, insulating layer, and connection metal layers function as a coaxial conductor.
