An electric power supply circuit includes an auxiliary electric power supply; a first MOSFET provided on an auxiliary electric power supply-side feed path, the first MOSFET including a parasitic diode configured to restrict conduction of electric current in a direction from the auxiliary electric power supply toward the feed target; a second MOSFET provided on the auxiliary electric power supply-side feed path, the second MOSFET including a parasitic diode configured to restrict conduction of the electric current in a direction from the feed target toward the auxiliary electric power supply; and a third MOSFET provided on at least one of the auxiliary electric power supply-side feed path and the main electric power supply-side feed path, the third MOSFET including a parasitic diode configured to restrict conduction of the electric current in a direction from the main electric power supply toward the auxiliary electric power supply.
