Abstract
A wiring substrate includes a core substrate including a through-hole conductor, a first resin insulating layer, a first conductor layer including a seed layer and an electrolytic plating layer, a via conductor formed such that the via conductor electrically connects the through-hole conductor and first conductor layer, and a second resin insulating layer covering the first conductor layer. The core substrate includes a glass substrate such that the through-hole conductor is penetrating through the glass substrate, the seed layer includes a first layer formed on the first resin insulating layer and a second layer formed on the first layer, and the first conductor layer includes a conductor circuit such that a width of the first layer is larger than a width of the second layer in the conductor circuit and a width of the electrolytic plating layer is larger than the width of the first layer in the conductor circuit.
