Claim:
1. A current sensor inspection system that inspects a current sensor that has a core made of a magnetic material and having the shape of a ring with a gap and a magnetometric sensor disposed in the gap and measures a current passing through a plane surrounded by the core by measuring a magnetic flux inside the core with the magnetometric sensor, the current sensor inspection system comprising: a first conductor and a second conductor passing through the plane surrounded by the core; a direct-current power supply device capable of supplying a direct current of 100 A or larger and outputting a value of a direct current; and an alternating-current power supply device capable of outputting a value of an alternating current, wherein the first conductor and the second conductor are insulated from each other, only the direct-current power supply device is connected to the first conductor, and only the alternating-current power supply device is connected to the second conductor.
