Claim:
1. A semiconductor device comprising: an insulating base material having a first upper surface and a first lower surface positioned on the opposite side of the first upper surface, a cavity on the first upper surface, and first terminals on the first lower surface; a semiconductor chip having a first top surface and a first back surface positioned on the opposite side of the first top surface, and an imaging unit on the first top surface side, and arranged in the cavity; a cap member sealing the cavity and having translucency; a mounting board having a second upper surface and a second lower surface positioned on the opposite side of the second upper surface, a through-hole, and second terminals on the second upper surface, and arranged in such a manner that the first terminals and the second terminals are electrically coupled to each other while allowing the first lower surface of the insulating base material to face the second upper surface; a heat transfer member inserted into the through-hole, and coupled to the insulating base material; and a heat radiation member arranged on the second lower surface side of the mounting board, and coupled to the heat transfer member, wherein first reinforcing terminals are provided at positions outside the arranged positions of the first terminals on the first lower surface of the insulating base material, and wherein second reinforcing terminals are provided at positions outside the arranged positions of the second terminals on the second lower surface of the mounting board.
