Semiconductor module
A semiconductor module that can be connected with simple wiring is provided. A semiconductor device of the semiconductor module is provided with a semiconductor substrate, a first electrode formed on one surface of the semiconductor substrate, and a second electrode formed on a surface of the semiconductor substrate opposite to the one surface. The semiconductor module is provided with a first electrode plate being in contact with the first electrode, a second electrode plate being in contact with the second electrode, and a first wiring member connected to the second electrode plate and penetrating the first electrode plate in a state of being insulated from the first electrode plate. The first electrode plate, the semiconductor device, and the second electrode plate are fixed with each other by an application of a pressure pressurizing the semiconductor device on the first electrode plate and the second electrode plate.
