Abstract
A current sensor configured to measure a current value of a current flowing through each of a first conductor, a second conductor, and a third conductor, the current sensor comprising: first to third magnetic detection units provided with detection surfaces and configured to output first to third detection result; first to third amplification factor correction units configured to correct first to third amplification factors set in advance based on an ambient temperature; first to third amplifiers configured to amplify the detection results based on the corrected amplification factors and output the amplified detection results as amplified signals; first to third influence degree correction units indicating influence degrees of the magnetic fields generated by the current flowing through the conductors; and first to third correction units configured to correct the amplified signals based on the corrected influence degrees and the amplified signals.
