Abstract: PROBLEM TO BE SOLVED: To obtain a power semiconductor device which prevents a partial discharge due to the exfoliation of an interface and due to the crack of an insulating substrate by a method wherein a resin whose specific gravity is smaller than that of at liquid insulator is injected onto the liquid insulator so as to be hardened as a sealing layer and the upper part of a case is sealed. SOLUTION: The pressure at the inside of a case 23 is decreased to about 0.1Torr. Then, as a sealing layer 10 which seals the upper part of the case 23, a liqdid insulator 12 whose specific gravity is larger than that of an epoxy resin is injected from an opening part on the surface of the case 23 up to a height which is higher than a control board 5. In addition, when the epoxy resin is injected from the opening part on the surface of the case 23 at atmospheric pressure, a layer by the epoxy resin is formed on the liquid insulator 12 because the specific gravity of the epoxy resin is lighter than that of the liquid insulator 12. An advantage to use the epoxy resin is that its bonding force to the case 23 is strong.  When a power semiconductor element 3 and the control board 5 are immersed in the liquid insulator 12, the liquid insulator 12 is used to suppress the generation of a creeping discharge on the surface of the power semiconductor element 3 and on the surface of the control board 5.
