Provided is a technique for a stably operable complementary single ended push pull (SEPP) circuit. A buffer circuit includes the following: an NPN transistor and a PNP transistor that constitute a complementary SEPP circuit; a first resistor; a second resistor; a first load element having one end connected to a gate of a semiconductor switching element and another end connected to a base of the NPN transistor; and a second load element having one end connected to the gate of the semiconductor switching element and another end connected to a base of the PNP transistor.
