Abstract
A current sensor is configured to measure current flowing in two bus bars aligned in an X direction and extending parallel in a Y direction. A sensing element is arranged such that its magnetism sensing direction is oriented in the X direction on a line passing through the bus bar in a Z direction. A pair of shield plates sandwiches the bus bar and the sensing element therebetween in the Z direction. The bus bar is located between the sensing element and the lower shield plate. The sensing element is located closer to the upper shield plate than to the lower shield plate. At least one of a thickness and a magnetic permeability of the magnetism shield plates is greater in the upper shield plate than in the lower shield plate.
