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 a magnetic material and are arranged to sandwich the busbar in a thickness direction of the busbar. The busbar includes a through-hole penetrating therethrough and current paths formed on both sides of the through-hole, the magnetic sensing element is arranged at a position overlapping the through-hole in the thickness direction of the busbar. The busbar is arranged in a space between the pair of shield plates such that the center in the thickness direction is located at a position offset from the center of the space in the thickness direction.
