Abstract
A printed wiring board includes a resin insulation layer having a first surface and a second surface on an opposite side of the first surface, the resin insulation layer having an opening for a via conductor, a pad formed on the first surface of the resin insulation layer and provided to mount an electronic component, a conductive circuit formed on the second surface of the resin insulation layer, and a via conductor formed in the opening and connecting the pad and the conductive circuit. The pad has an embedded portion embedded in the resin insulation layer and a protruding portion protruding from the resin insulation layer, and the embedded portion has an external shape which is greater than an external shape the protruding portion.
