    Abstract: A printed wiring board includes a first conductor layer, a resin insulating layer formed on the first conductor layer, a second conductor layer formed on a surface of the resin insulating layer, and a via conductor formed in the resin insulating layer such that the via conductor is connecting the first and second conductor layers and has a land portion extending on a boundary part of the resin insulating layer. The via conductor is formed in a via hole formed in the resin insulating layer. The resin insulating layer is formed such that the boundary part has a surface roughness that is larger than a surface roughness of the surface on which the second conductor layer formed and that an inner wall surface in the via hole in the resin insulating layer is equal to or larger than the surface roughness of the boundary part of the resin insulating layer.
