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 device 1 is connectable to a control board 100 detecting a current flowing through an IGBT 3 included in the semiconductor device 1 and functioning as a semiconductor element. The semiconductor device 1 includes an insulating substrate, the IGBT 3, and a sense resistor 4. The IGBT 3 is disposed on the insulating substrate 2, and includes a sense electrode and an emitter electrode. The sense resistor 4 is disposed on the insulating substrate 2, and has one end connected to the sense electrode and the other end connected to the emitter electrode. The control board 100 detects a potential difference between both ends of the sense resistor 4 to detect the current flowing through the IGBT 3.
