PROBLEM TO BE SOLVED: To provide a current sensor abnormality determination device capable of increasing opportunities for abnormality determination. SOLUTION: A current sensor abnormality determination device includes: means for determining S40 or S70) that a current sensor has abnormality in the case of a detection value of the current sensor≥a charge time threshold THin during battery charging or in the case of the detection value of the current sensor≤a discharge time threshold THout during battery discharging; and means for setting the charge time threshold THin at a maximum generated current value (max alternator current), and setting the discharge time threshold THout at a total (max consumption current) of maximum consumption current of multiple electric loads installed in a vehicle. A battery current IB at the time of charging should not exceed a value less than the max alternator current, and the battery current IB at the time of discharging should not exceed the max consumption current. Therefore, the means for setting the thresholds THin and THout based on the max alternator current and the max consumption current enables the current sensor abnormality determination device to determine abnormality during discharging and charging and to increase opportunities for the determination.
