The magnets are spaced apart in the direction of the linear displacement and fixed to the movable member so as to have opposite polarities, one end facing the outer end surface of the first magnet, and the other end facing the second magnet. A magnetic path member facing the outer end surface of the magnet and a magnetic flux density detection means for detecting the magnetic flux density passing through the magnetic path member are provided on the fixed member that is relatively displaceable with respect to the movable member, and further, and a displacement sensor, characterized in that a third magnet is provided on the magnetic path member in a direction in which magnetic flux is generated in the same direction as the magnetic flux generated by the second magnet. (2) A displacement sensor that detects the axial displacement of a shaft that rotates and moves in the axial direction, in which ring-shaped first and second magnets having opposite polarity in the radial direction a magnetic path member that is spaced apart and externally fitted on the shaft, and has one end facing the outer circumferential surface of the first magnet and the other end facing the outer circumferential surface of the second magnet; and this magnetic path member. a magnetic flux density detection means for detecting the magnetic flux density passing through the shaft, the fixed member being displaceable relative to the axis;
and a displacement sensor, characterized in that a third magnet is provided on the magnetic path member in a direction in which magnetic flux is generated in the same direction as the magnetic flux generated by the second magnet.
