Abstract: A semiconductor device includes a package and a cooler. The semiconductor package includes a semiconductor element, a metal member, and a molding member for encapsulating the semiconductor element and the metal member. The metal member has a metal portion thermally connected to the semiconductor element, an insulating layer on the metal portion, and a conducting layer on the insulating layer. The conducting layer is at least partially exposed outside the molding member and serves as a radiation surface for radiating heat of the semiconductor element. The cooler has a coolant passage through which a coolant circulates to cool the conducting layer. The conducting layer and the cooler are electrically connected together.

Abstract: In a power converter, electronic components constituting a power conversion circuit is provided. A capacitor module and a converter case are also provided in the power converter. Fastening members, which include a first fastening member and a second fastening member, are configured to fasten the capacitor module to the converter case. The first and second fastening members are mounted on the inner bottom surface of the converter case. At least one of the electronic components is mounted to the capacitor module and is arranged between the first fastening member and the second fastening member when viewed in a view direction perpendicular to an alignment direction of the first and second fastening members. The view direction is parallel to the inner bottom surface of the converter case.
