Abstract
A wiring substrate includes an insulating layer having through holes, a first conductor layer formed on first surface of the insulating layer, a second conductor layer formed on second surface of the insulating layer, and interlayer conductors formed along wall surfaces surrounding the through holes such that each interlayer conductor has a film-like shape and is connecting the first and second conductor layers. The interlayer conductors include first conductors formed in first region of the insulating layer and second conductors formed in second region of the insulating layer at density higher than density of the first conductors, and a thickness of each first interlayer conductor in its end part is substantially same as or larger than a thickness of each second conductor in its end part and a thickness of each first conductor in its center part is larger than a thickness of each second conductor in its center part.
