Abstract
A wiring substrate includes an insulating layer, a conductor layer formed on surface of the insulating layer and including a conductor pad, a covering layer covering a portion of the insulating layer, an optical waveguide positioned on the surface of the insulating layer and including core part, and a conductor post including plating metal and formed on the conductor pad such that the post is penetrating through the covering layer and connected to a component. The insulating layer has component region covered by the component when the component is connected, the core part has side surface extending in direction along the surface of the insulating layer, the side surface has an exposed portion exposed in the component region and facing the opposite direction with respect to the insulating layer, and distance between the exposed portion and the surface of the insulating layer is greater than thickness of the covering layer.
