Abstract
A wiring substrate includes a core substrate having a first main surface and a mutually opposing second main surface, the second main surface having a conductive property. A first through hole penetrates a core substrate. A first conductive layer extends from the first main surface to the second main surface via the first through hole. An insulating layer is formed on the first conductive layer. A second through hole has the insulating layer as an interior wall. And a second conductive layer is formed inside the second through hole.
