Abstract
A printed wiring board, including a printed wiring member which respectively has object conductor that is subjected to electromagnetic wave shielding on at least one surface of an insulating layer; and an electromagnetic wave shielding member which has an electromagnetic wave shielding layer composed of a low-resistance section and a high-resistance section on at least one surface of a base film. The printed wiring member and the electromagnetic wave shielding member are bonded together with interposition of insulating adhesive layers, and with arrangement of the electromagnetic wave shielding layer separately and in opposition so that the object conductor is covered. The electromagnetic wave shielding layer and the object conductor are composed of the same type of conductive material, and the electromagnetic wave shielding layer is not exposed at the circumferential end faces of the printed wiring board.
