Abstract
A semiconductor module, including: plurality of output elements provided to constitute an upper arm and a lower arm; a resin case provided surrounding an accommodation space for accommodating the output elements; an arm-to-arm wiring line for connecting the upper arm with the lower arm; an output terminal, which is connected to the arm-to-arm wiring line and is for outputting output currents from the output elements to a load being external to the semiconductor module; a sense terminal, which is connected to the arm-to-arm wiring line and is for detecting currents that flow in the output elements; and an inductor provided between a connection point for connecting the arm-to-arm wiring line with the output terminal, and the output terminal is provided. An inductance of the inductor is 1 μH or more.
