Claim 17:
18. A magnetic sensor configured to detect a magnetic field to be detected having a first direction at a reference position within a first plane, and generate a detection value corresponding to a relative position of the magnetic sensor with respect to a magnetic field generation source of the magnetic field to be detected, wherein:
the magnetic sensor includes a magnetoresistive element;
the magnetoresistive element includes a first magnetic layer having first magnetization that can change in direction within a second plane corresponding to the magnetoresistive element, the second plane being oblique to the first plane;
the magnetic field to be detected received by the magnetoresistive element includes an in-plane component parallel to the second plane, the in-plane component having a second direction that changes with a change in the first direction;
the first magnetic layer is configured such that the direction of the first magnetization changes with a change in the second direction;
the detection value depends on the direction of the first magnetization; and
the magnetic sensor is configured such that as the relative position of the magnetic sensor with respect to the magnetic field generation source changes, the first direction changes within a predetermined variable range in the first plane.
