Abstract
A power module will be provided which can suppress insulation performance deterioration caused by heat cycle to ensure insulation performance, by suppressing generation of bubbles and occurrence of detachments between silicone gel and an insulating substrate at a high or low temperature or at a high working voltage. The power module includes: an insulating substrateon a first face of which a semiconductor elementis provided; a base platejoined to a second face of the insulating substrate; a case membersurrounding the insulating substrateand being in contact with a face of the base plate, that is joined to the insulating place; sealing resinfilling a region surrounded by the base plateand the case memberto seal the insulating substrate; a pressing platedisposed in close contact with a surface of the sealing resinin a side of the first face of the insulating substrate; and a lid memberfacing an opposite face of the pressing platewith respect to a face thereof in close contact with the sealing resin, and being fixed to the case memberat a position to prevent the pressing platefrom ascending.
