Abstract
A magnetic sensor includes a magnetoresistive element having a sensitivity axis in a Y direction, a magnetic shield disposed apart in a Z direction from the magnetoresistive element and configured to attenuate the intensity of a magnetic field to be measured, and a magnetic balance coil. The magnetic shield includes a first shield part longitudinally extending in the X direction and second shield parts provided on either side of the first shield part. The first shield part has a portion that overlaps the magnetoresistive element when viewed in the Z direction. Each second shield part has a portion that overlaps the magnetoresistive element when viewed in the X direction. A magnetic path for a magnetic field in the X direction can be formed from one of the second shield parts to the other one of the second shield parts via the first shield part.
