Abstract
A current sensor includes a first magnetic sensor and a second magnetic sensor which are configured to detect an induced magnetic field from target current to be measured flowing through a current line. The first and second magnetic sensors each include a magnetoresistive element that includes a free magnetic layer and a hard bias layer applying a bias magnetic field to the free magnetic layer. The bias magnetic field in the magnetoresistive element of the first magnetic sensor is oriented opposite to the bias magnetic field in the magnetoresistive element of the second magnetic sensor.
