Abstract: A current sensor includes a magnetic detection element configured to detect magnetism produced from a current path and a magnetic shield core. The magnetic shield core includes a core portion arranged so as to extend around the current path such that the current path is positioned therein, a gap portion formed by cutting a part of the core portion and in which the magnetic detection element is arranged, and at least a pair of shield portions extending from the core portion toward the outside opposite to the inside of the core portion where the current path is arranged, so as to correspond to the magnetic detection element.

Abstract: A current sensor to be provided in a current path through which current flows includes a housing, a substrate accommodated in the housing, a plurality of magnetic detection elements mounted on the substrate, and a pair of shields respectively disposed on both sides of each magnetic detection element. The shields are accommodated in the housing so as to surround the current path on both sides of the current path and the shields are held so that respective end portions of the shields have a predetermined interval. The magnetic detection elements and the shields are disposed in each phase current path for three-phase AC.
