Abstract
A wiring substrate includes a buried substrate disposed within a through-hole penetrating through a resin substrate of a core layer and including a plate-like body and a plurality of linear conductors penetrating the plate-like body, a first insulating layer covering a first surface of the resin substrate, a first wiring layer including a first pad pattern formed on a first surface of the buried substrate and a first wiring pattern formed on a first surface of the first insulating layer, and a third wiring pattern formed on the first surface of the resin substrate and covered by the first insulating layer. In the plurality of linear conductors, a gap between the adjacent linear conductors is smaller than a diameter of each of the linear conductors. The third wiring pattern is formed so as to have a thickness thicker than a thickness of the first wiring pattern.
