PROBLEM TO BE SOLVED: To provide a stroke sensor which can be downsized by facilitating wiring of a wire cord.SOLUTION: The stroke sensor includes: a first unit 1 which includes an elastic member 4 for energizing a shaft 3 provided with a magnet 2 toward a detection object and a first case body 7 comprising a large-diameter cylindrical part 5 and a small-diameter cylindrical part 6 in which the shaft 3 including the magnet 2 and the elastic member 4 are housed; and a second unit U2 which includes a magnetic detection element 11a for outputting an electric signal corresponding to displacement of the shaft 3, a circuit board 12 having the magnetic detection element 11a mounted thereon, an electric cord 13 drawn out from the circuit board 12, and an insertion part 14a through which the small-diameter cylindrical part 6 is inserted and has the magnetic detection element 11a, the circuit board 12, and a part of the electric cord 13 housed in the second case body 14. The second unit U2 is fixedly held on the first unit U1 via a fixing member 16. |
