Abstract
A wiring substrate includes a core substrate, a first build-up part formed on a first surface of the substrate and including insulating layers and conductor layers, and a second build-up part formed on a second surface of the substate on the opposite side with respect to the first surface and including insulating layers and conductor layers. The first build-up part includes a first region and a second region such that a distance between adjacent conductor layers in the second region is smaller than a distance between adjacent conductor layers in the first region, the conductor layers in the second region include second wirings having the minimum wiring width and the minimum inter-wiring distance that are smaller than the minimum wiring width and the minimum inter-wiring distance of first wirings of the conductor layers in the first region and the insulating layers are continuous in the first region and second region.
