A vehicle electric power control apparatus includes semiconductor fuses, current sensors, an interlayer short-circuit determination unit, and a switching unit. The semiconductor fuses are disposed between a vehicle power supply and respective vehicle auxiliary devices. The current sensors detect current values flowing through the respective semiconductor fuses. The interlayer short-circuit determination unit makes a determination as to occurrence of an interlayer short-circuit between any of the semiconductor fuses and a corresponding one of the vehicle auxiliary devices, on the condition that a second current detection value inputted from the corresponding one of the vehicle auxiliary devices differs from an allowable value of a first current detection value inputted from a corresponding one of the current sensors. The switching unit switches, to off-operation, the any of the semiconductor fuses on a path related to the determination as to the occurrence of the interlayer short-circuit.
