1. A magnetic sensor for detecting a position of a magnet in a first direction, comprising:
a magnet magnetized in the first direction; and two magnetic sensor elements, wherein the two magnetic sensor elements are spaced apart from each other in a second direction orthogonal to the first direction and face the magnet in a third direction orthogonal to the first direction and the second direction, a soft magnetic body is provided between the magnet and the two magnetic sensor elements in the third direction and located between the two magnetic sensor elements in the second direction, the two magnetic sensor elements each have a fixed magnetic layer in which magnetization is fixed, and a free magnetic layer in which magnetization changes due to an external magnetic field, and are provided in a range in which magnetic flux which is generated from the magnet saturates magnetization of the free magnetic layers of the two magnetic sensor elements, wherein magnetization directions of the 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. |
