Abstract
A position sensor of the present invention includes: a magnet that moves together with a moving body; a magnetic sensor that detects a magnetic flux generated by the magnet; and a detector that detects an anomaly of the magnetic sensor based on a detection value detected by the magnetic sensor. The magnetic sensor is set so as to detect the detection value taking a value on a locus preset in accordance with a position of the moving body, and the locus is set so that a change rate of the detection value corresponding to change of the position of the moving body differs for each of a plurality of sections set within a movement range of the moving body. The detector detects the anomaly of the magnetic sensor based on a relation between the detection value and a comparison value that is a value corresponding to the locus.
