Abstract
A magnetic sensor for detecting the position of a magnet in an X direction includes two magnetic sensor elements which are disposed to be spaced apart from each other in a Y direction and are disposed to face the magnet in a Z direction, in which a soft magnetic body is provided to be located between the magnet and the two magnetic sensor elements and to be located between the two magnetic sensor elements, the two magnetic sensor elements are provided in a range in which magnetic flux which is generated from the magnet saturates magnetization of free magnetic layers of the two magnetic sensor elements, magnetization directions of fixed magnetic layers of the two magnetic sensor elements are the same as each other, and a bridge circuit is configured with the two magnetic sensor elements.
