Abstract:
1. A wiring substrate comprising: a core substrate including a first main surface, a second main surface, and a through hole; an electronic component including a resin cover and arranged in the through hole; a projection that projects from an inner wall of the through hole toward the resin cover of the electronic component so that the projection contacts a part of an outer surface of the resin cover while the remainder of the outer surface of the resin cover is spaced from contact with the inner wall of the through hole to form an empty space; an insulator that fills the empty space between the inner wall of the through hole and the electronic component; a first insulation layer that covers the electronic component and the first main surface of the core substrate; a second insulation layer that covers the electronic component and the second main surface of the core substrate; and an engagement groove that is formed in the resin cover of the electronic component and is engaged with the projection, extending along a direction in which the electronic component is fitted into the through hole.
