A configuration with which, even if the supply of power from a power supply portion ceases, the power from another power supply source can be instantly supplied to a power supply target is more easily achieved. In a backup circuit, a control unit causes a second voltage conversion portion to perform a voltage conversion operation in response to satisfaction of a predetermined first backup condition, and a power supply portion-side conductive path and an electricity storage portion-side conductive path are electrically connected to each other via a resistive portion when the control unit is causing the second voltage conversion portion to perform the voltage conversion operation. Furthermore, the control unit causes the first voltage conversion portion to perform a second operation in response to a predetermined second backup condition being satisfied when the control unit is causing the second voltage conversion portion to perform the voltage conversion operation.
