Abstract
A magnetic sensor includes a magnetic-field detector including magneto-resistance elements, and a shield. Since the feedback coil is disposed so as to overlap with the magnetic-field detector, and the shield is disposed so as to overlap with the feedback coil, the cancellation field of the feedback coil makes it difficult to cause magnetization saturation. The shield is annular in shape as viewed from a direction normal to the shield. This allows maintaining the magnetic-field shielding action of the shield to enhance the effect of shielding the magnetic field in a direction perpendicular to the sensitivity.
