Abstract

A current sensor includes a first current path, a second current path disposed parallel to the first current path, and a pair of first magnetic sensors. The first current path has a pair of main surfaces and includes a plate-shaped first region. The second current path has a pair of main surfaces and includes a plate-shaped second region. The first magnetic sensors are arranged on the respective main surfaces in the first region such that sensing axes of the first magnetic sensors are parallel to the respective main surfaces in the first region. The first magnetic sensors are configured to sense a magnetic field generated by a target current flowing through the first region. The second region is placed such that the main surfaces in the second region are perpendicular to the sensing axes of the first magnetic sensors.
