Abstract
A power semiconductor device includes a circuit body, first and second insulations, first and second bases, a case, and a distance regulation portion. The circuit body incudes a semiconductor element and a conductive portion. The first insulation and the second insulation oppose each other. The first base and second base also oppose each other. The case has a first opening portion covered with the first base and a second opening portion covered with the second base. The distance regulation portion has a first end that contacts the first base and a second end, that is opposite to the first end, and that contacts the second base. The distance regulation portion regulates a distance between the first base and the second base.
