The invention discloses an electric power supply circuit and an electric power supply device. The electric power supply circuit includes an auxiliary electric power supply (100); a first MOSFET (101)provided on an auxiliary electric power supply-side feed path, the first MOSFET (101) including a parasitic diode configured to restrict conduction of electric current in a direction from the auxiliary electric power supply (100) toward the feed target; a second MOSFET (102) provided on the auxiliary electric power supply-side feed path, the second MOSFET (102) 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 (100); and a third MOSFET (103) 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 (103) including a parasitic diode configured to restrict conduction of the electric currentin a direction from the main electric power supply toward the auxiliary electric power supply (100).
