Abstract: A wiring substrate includes: a first insulating layer; a ground plane formed on the first insulating layer; a second insulating layer formed on the first insulating layer such that the ground plane is covered with the second insulating layer; a first signal wiring formed on the second insulating layer; a third insulating layer formed on the second insulating layer such that the first signal wiring is covered with the third insulating layer; and a second signal wiring formed on the third insulating layer and electrically connected with the first signal wiring. The first signal wiring is arranged in a region overlapping with a portion of a heat radiating plate. The second signal wiring is not arranged in the region. The ground plane has an opening portion located at a position overlapping with the first signal wiring. The opening portion is formed so as to extend along the first signal wiring.
