Abstract: A position sensor includes a detector (122) and a signal processor (123). The detector generates detection signals, which have a distinct phase difference and which respectively correspond to ranges aligned in one direction along a movement direction of a detection target (200, 202, 203) having a magnetic material, based on a change in a magnetic field received from the detection target along with a movement of the detection target. The signal processor acquires the detection signals from the detector, compares the detection signals with a threshold value, and specifies a position of the detection target as a position covered by one of the ranges based on a combination of magnitude relations of the detection signals and the threshold value.
