Abstract
A wiring substrate includes a first build-up part including first insulating layers, first conductor layers formed on the first insulating layers, and first via conductors formed in the first insulating layers, and a second build-up part laminated to the first build-up part and including second insulating layers, second conductor layers formed on the second insulating layers, and second via conductors formed in the second insulating layers. A wiring width and an inter-wiring distance of wirings in the first conductor layers of the first build-up part are smaller than a wiring width and an inter-wiring distance of wirings in the second conductor layers of the second build-up part, and the first build-up part is formed such that the first insulating layers include insulating resin and inorganic particles and that the insulating resin in the first insulating layers forms the surfaces of the first insulating layers covered by the first conductor layers.
