Abstract
A current sensor includes a magnetic sensor device. The magnetic sensor device includes a magnetic sensor, a first magnetic layer, and a second magnetic layer in non-contact with the first magnetic layer. The magnetic sensor, the first magnetic layer, and the second magnetic layer are disposed across a virtual straight line and arranged in this order in a direction parallel to the virtual straight line. Different portions of magnetic flux generated by a current to be detected pass through the magnetic sensor, the first magnetic layer, and the second magnetic layer.
