To provide a contactor failure determination apparatus capable of appropriately determining failure of a contactor provided in a vehicle, a voltage sensor capable of detecting rising or dropping of a voltage of a second circuit including an external charger is provided. When an external charging request is made, a first control for closing each external charging contactor is executed, a second control for closing a pre-charge contactor is executed after execution of the first control, a third control for closing a second main contactor is executed after execution of the second control, and response to the voltage sensor detecting that the voltage of the second circuit has not risen after execution of the third control, it is determined that at least one of the external charging contactors has failed in an open state.
