A torque sensor is provided with: a pedestal part (20, 70, 100, 110, 120, 130, 140, 150) that is secured to a rod-shaped metallic shaft (10) the strain of which is to be measured; an SAW-type strain detection element (40) that is disposed on the pedestal part (20, 70, 100, 110, 120, 130, 140, 150), and detects the strain of the metallic shaft (10) via the pedestal part (20, 70, 100, 110, 120, 130, 140, 150); and a securing part (30) that is disposed between the pedestal part (20, 70, 100, 110, 120, 130, 140, 150) and the strain detection element (40), and secures the strain detection element (40) to the pedestal part (20, 70, 100, 110, 120, 130, 140, 150). La présente invention concerne un capteur de couple comprenant : une partie socle (20, 70, 100, 110, 120, 130, 140, 150) qui est fixée à un arbre métallique en forme de tige (10) dont la déformation doit être mesurée ; un élément de détection de déformation de type SAW (40) qui est disposé sur la partie socle (20, 70, 100, 110, 120, 130, 140, 150) et qui détecte la déformation de l'arbre métallique (10) par l'intermédiaire de la partie socle (20, 70, 100, 110, 120, 130, 140, 150) ; et une partie fixation (30) qui est disposée entre la partie socle (20, 70, 100, 110, 120, 130, 140, 150) et l'élément de détection de déformation (40) et qui fixe l'élément de détection de déformation (40) à la partie socle (20, 70, 100, 110, 120, 130, 140, 150).
