To provide a displacement sensor that increases a degree of freedom in being mounted to a structure and is compact and light, and to provide a vehicle height sensor using it.SOLUTION: A displacement sensor 1 includes oscillation means 3, a detection part 2, and a signal processing part 4. The detection part 2 has a bobbin 10, a detection coil 15, and a wire 20 obtained by twisting a metal wire. A high-frequency magnetic field is generated in a hollow part 11 of the bobbin 10 by the detection coil 15. For the wire 20, one end 20a is inserted into the hollow part 11 and the other end 20b is connected with a moving body 5. The wire 20 has at least one of magnetic permeability and conductivity, and has moderate flexibility and elasticity. The wire 20 is curved between the detection part 2 and the moving body 5. The moving body 5, a displacement direction 5b of the moving body, the wire 20, and the detection part 2 does not need to be disposed in a line, thus allowing for being mounted with a high degree of freedom.SELECTED DRAWING: Figure 1

    【課題】構造体への取付時における自由度を高めると共に、小型で軽量である変位センサおよびこれを用いた車高センサを提供する。【解決手段】変位センサ1は、発振手段3と検出部2と信号処理部4とを有する。検出部2は、ボビン10と検出コイル15と金属線を縒り合わせたワイヤ20を有する。ボビン10の中空部11には検出コイル15によって高周波磁界が発生している。ワイヤ20は、一端20aが中空部11に挿入され、他端20bが移動体5と連結している。ワイヤ20は、透磁性および導電性の少なくとも一方を有し、かつ適度な柔軟性および弾性を有する。ワイヤ20は、検出部2と移動体5の間で湾曲している。移動体5、移動体の変位方向5b、ワイヤ20、検出部2を一直線上に配置する必要がなく、自由度の高い取付が可能となる。【選択図】図1
