[Task] To provide a contactor failure determination apparatus capable of appropriately determining failure of a contactor provided in a vehicle.[Solution] A detector 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, first control for closing each external charging contactor is executed, second control for closing a precharge contactor is executed after execution of the first control, third control for closing a second main contactor is executed after execution of the second control, and, when the detector detects that the voltage of the second circuit is not risen after execution of the third control, it is determined that at least one of the external charging contactors fails in an open state.
