    Abstract: A printed wiring board includes a core substrate, a first build-up layer, and a second build-up layer. The core substrate includes a core layer, through-hole conductors and through-hole lands. Metal foils of the through-hole lands in the core substrate have mat surfaces at interfaces of the core layer in the core substrate, metal foils of via lands in the build-up layers have inner mat surfaces at interfaces of insulating layers, and metal foils of outermost conductor layers in the build-up layers have outermost mat surfaces at interfaces of outermost insulating layers. Ten-point average roughness (RzI1) of the inner first mat surface is smaller than each often-point average roughness (Rz1, Rz2) of the mat surfaces and ten-point average roughness (RzO1, RzO2) of the outermost mat surfaces. Ten-point average roughness (RzI2) of the inner second mat surface is smaller than each of the ten-point average roughness (Rz1, Rz2, RzO1, RzO2).
