In a semiconductor device including a plurality of insulated gate switching cells each of which has a gate electrode, an emitter electrode that is commonly provided to cover the plurality of insulated gate switching cells, and a bonding wire connected to the emitter electrode, a gate driving voltage being applied to the gate electrode of each insulated gate switching cell so that emitter current flows through the emitter electrode, mutual conductance of each insulated gate switching cell is varied in accordance with the distance from the connection portion corresponding to the bonding position of the bonding wire so that the emitter current flowing through the emitter electrode is substantially equal among the plurality of insulated gate switching cells. |
