Current sensor

Abstract

A current sensor includes a busbar carrying an electric current to be measured, a magnetic sensing element for detecting intensity of a magnetic field generated by the current flowing through the busbar, and a pair of shield plates that include magnetic materials and are arranged to sandwich the busbar in a thickness direction of the busbar. The shield plates include a conductive shield plate including a conductive magnetic material and a non-conductive shield plate including a non-conductive magnetic material. The conductive shield plate includes a slit penetrating therethrough. The magnetic sensing element is arranged at a position where the magnetic sensing element overlaps the slits in the thickness direction and does not overlap the conductive shield plate in the thickness direction.
