The purpose of the present invention is to ensure a heat source, while suppressing a weight increase and a cost increase. A drive apparatus (85) drives a switching element constituted by a transistor that includes a high-heat resistant semiconductor including silicon carbide. The drive apparatus (85) is provided with a voltage adjusting unit (93) that varies a drive voltage to be applied to a conduction control terminal of the switching element in order to put the switching element in an on state, and the voltage adjusting unit (93) applies, as the drive voltage, a voltage in an active region of the transistor to the conduction control terminal.
