A position sensor is provided that can detect a position along a long stroke and that can limit an increase in size.A magnetic sensor has a first magnetic field detecting element that is positioned in a first track; a first processor 4A that outputs voltage VM1 when intensity of a first magnetic field that is applied to the first magnetic field detecting element is equal to or larger than a threshold and that outputs predetermined high voltage VH when the intensity of the first magnetic field is less than the threshold, wherein the voltage VM1 is voltage between predetermined low voltage VL and the high voltage VH and indicates positions of the magnets relative to the first magnetic field detecting element; a second magnetic field detecting element that is positioned in a second track; and a second processor 4B that outputs the low voltage VL when intensity of a second magnetic field that is applied to the second magnetic field detecting element is less than the threshold and that outputs voltage VM2 when the intensity of the second magnetic field is equal to or larger than the threshold, wherein the voltage VM2 is voltage between the low voltage VL and the high voltage VH and indicates positions of the magnets relative to the second magnetic field detecting element.
