[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 a vehicle start request is made, first control for closing one external charging contactor is executed, second control for closing a pre-charge contactor is executed after execution of the first control, third control for closing a main contactor, which is not parallel with the pre-charge contactor, is executed after execution of the second control, and, when the detector detects that the voltage of the second circuit is risen after execution of the third control, it is determined that the other external charging contactor fails in a closed state.
