A package for a semiconductor device according to the present invention includes at least one through hole 6 provided on at least one of lead frames 1 and 2. Thus when resin is injected to form a mounting region 4 of a semiconductor element while holding the lead frames 1 and 2, the resin can be injected from the back sides of the lead frames 1 and 2 through the through hole 6 serving as a resin flow path, thereby shortening the resin flow path and suppressing the occurrence of portions unfilled with the resin and poor appearances. |
