Abstract
An object is to provide a semiconductor device that can prevent increase in the package size and detect a current with high precision by suppressing a current induced by magnetic flux. A semiconductor deviceis connectable to a control boarddetecting a current flowing through an IGBTincluded in the semiconductor deviceand functioning as a semiconductor element. The semiconductor deviceincludes an insulating substrate, the IGBT, and a sense resistor. The IGBTis disposed on the insulating substrate, and includes a sense electrode and an emitter electrode. The sense resistoris disposed on the insulating substrate, and has one end connected to the sense electrode and the other end connected to the emitter electrode. The control boarddetects a potential difference between both ends of the sense resistorto detect the current flowing through the IGBT
