サ。 A cylindrical casing, a magnetostrictive shaft rotatably disposed within the casing, a cylindrical coil bobbin disposed within the casing so as to surround the outer circumference of the magnetostrictive shaft, and a coil bobbin acting on the magnetostrictive shaft. A magnetostrictive torque sensor comprising at least a pair of detection coils located between the coil bobbin and a casing and wound around the coil bobbin in order to detect the torque generated by the coil bobbin as an electric signal. The magnetostrictive torque sensor is characterized in that a ventilation passage for circulating air is formed along the axial direction of the coil bobbin on the outer peripheral side of each of the detection coils.
