Abstract
A magnetostrictive torque sensor includes first to fourth detection coils each wound around a steering axle (a sensor shaft) so as to surround a magnetostrictive film formed on the sensor shaft and a multi-turn winding bias coil that is separated from the first to fourth detection coils and that is wound around the sensor shaft so as to surround the magnetostrictive film. By applying a DC component current to the bias coil, a sufficient bias magnetic field is applied to the magnetostrictive film so that the hysteresis is prevented.
