An integrated circuit that drives a switching device provided between a first line on a ground side and a second line on a power supply side, when a power supply voltage is applied between a first input terminal connected with a first capacitor and a second input terminal, the first capacitor having one end grounded and another end connected to the first input terminal, the integrated circuit includes: a first terminal connected to a circuit element, the circuit element having one end grounded and another end connected to the first terminal; and a drive circuit that changes a voltage at the first terminal to one logic level when a drive signal of the switching device changes to the one logic level, and changes the voltage at the first terminal to another logic level when the drive signal changes to the other logic level.
