A semiconductor device includes a semiconductor chip having a source electrode on the front surface thereof, a diode that has an anode electrode on the front surface thereof, and a first conductive member through which output signals from the source electrode pass. The semiconductor device further includes a first wiring member that electrically connects the source electrode and the first conductive member, and a second wiring member that electrically connects the anode electrode and the first conductive member and that has a wider surface area than the first wiring member. The semiconductor device includes a second conductive member where the semiconductor chip and the diode are arranged.
