PROBLEM TO BE SOLVED: To accurately detect a current value.SOLUTION: A current sensor 10 that is provided with a magnetic resistance element 11 measures a current to a load A to be measured, on the basis of two output changes of an output change (output change due to a sense current unit 12) according to a sense current flowing in the magnetic resistance element 11 itself and an output change according to a current to an electric wiring (output change due to the influence of an electric wiring wd2 or the like) arranged near the magnetic resistance element, of the magnetic resistance element 11. |
