Abstract

A wiring substrate includes a wiring layer and an insulation layer covering the wiring layer. The insulation layer includes an opening partially exposing the wiring layer. A seed layer continuously covers a wall surface of the opening and an upper surface of the insulation layer. The wiring substrate also includes a metal layer, a metal post, and an outer coating plating layer. The opening is filled with the seed layer and the metal layer formed on the seed layer. The metal post is formed on the metal layer and on the seed layer that is located on the insulation layer. The outer coating plating layer includes an upper portion, entirely covering an upper surface of the metal post, and a side portion, entirely covering a side surface of the metal post and exposing an outer end surface of the seed layer. The side portion is thinner than the upper portion.
