Among first IGBTs and first MOSFETs, a transistor arranged near a first gate control circuit gives, through a gate thereof, a gate control signal supplied from the first gate control circuit to a gate of a transistor arranged at a position farther from the first gate control circuit. Among second IGBTs and second MOSFETs, a transistor arranged near a second gate control circuit gives, through a gate thereof, a gate control signal supplied from the second gate control circuit to a gate of a transistor arranged at a position farther from the second gate control circuit.
