A drive circuit for a voltage driven type semiconductor element, includes: an electrical charge discharge unit that discharges electrical charge from a gate terminal of a voltage driven type semiconductor element when the voltage driven type semiconductor element is turned OFF; and an electrical discharge control unit that detects a time variation of a collector voltage of the voltage driven type semiconductor element, and controls electric discharge by the electrical charge discharge unit according to the time variation of the collector voltage which has been detected.
