  • Publication number: 20240274511
    Abstract: A semiconductor module includes a semiconductor element, a heat dissipation member thermally connected to the semiconductor element, a resin member, a signal terminal, and a wiring member. The resin member accommodates the semiconductor element, the heat dissipation member, and the wiring member. At least a part of the heat dissipation member is exposed from the resin member. The wiring member is a member more flexible than the signal terminal, and includes an electrically insulating resin layer and a metal layer supported by the resin layer. The wiring member connects a signal pad of the semiconductor element and the signal terminal.
