<p>A distortion sensor capable of improving the detection accuracy without any fluctuation in the bending stress exerted on a distortion detection element. A sensor substrate has a first fixed hole in one end side and a second fixed hole in the other end side, and a detection hole in a center part, and also at least one distortion detection element on either an upper surface or a lower surface thereof. A first fixing member is press-fitted in the first fixed hole, and the second fixing member is press-fitted to the second fixed hole. A detection member is press-fitted to the detection hole. In addition, the distortion detection element detects the distortion caused by the movement of the position of the detection member with respect to the first fixing member and the second fixing member when the external force is applied to the detection member.</p> |
