Abstract 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. L'invention concerne un capteur de distorsions à précision de détection améliorée, mais sans fluctuation de la contrainte de flexion qui s'exerce sur un élément de détection de distorsion. Un substrat de capteur comporte un premier trou fixe sur une extrémité latérale, un second trou fixe sur l'autre extrémité latérale, et un trou de détection dans une partie centrale, ainsi qu'au moins un élément de détection de distorsion sur une surface supérieure ou inférieure du substrat. Une première pièce de fixation est insérée à la force dans le premier trou, et une seconde pièce de fixation est insérée à la force dans le second trou. Un élément de détection est inséré à la force dans le trou de détection. De surcroît, l'élément de détection de distorsion détecte la distorsion qui résulte du mouvement de la position de l'élément par rapport aux première et seconde pièces de fixation lorsque la force externe s'applique à cet élément.
