Printed wiring board having connecting terminals for electrically connecting conductor layers, circuit module having printed wiring board, and manufacturing method for printed wiring board

摘要

A printed wiring board comprises a substrate having a plurality of conductor layers and an insulating layer interposed between the conductor layers and a connecting terminal electrically connecting the conductor layers. The connecting terminal includes a shaft portion penetrating the insulating layer and having a distal end in contact with one of the conductor layers, and a head portion situated on the side opposite from the distal end of the shaft portion and in contact with another one of the conductor layers.
