Abstract
A wiring substrate includes a first build-up part including first insulating and conductor layers, and via conductors, and a second build-up part including second insulating and conductor layers. The first build-up part is laminated on the second build-up part. The minimum wiring width of wirings in the first conductor layers is smaller than the minimum wiring width of wirings in the second conductor layers. The minimum inter-wiring distance of the wirings in the first conductor layers is smaller than the minimum inter-wiring distance of the wirings in the second conductor layers. The first conductor layers and via conductors include a first layer and a second layer. The first layer of each via conductor is covering inner wall surface in a via opening and has a first portion and a second portion. The first portion has a portion formed closer to the center of the via opening than the second portion.
