摘要：
A magnetostrictive torque sensor comprising: a magnetostrictive film provided on a ferromagnetic shaft; a bias magnetization device which applies a bias magnetic field to the shaft to magnetize the shaft; and a detection device which detects a change in magnetism of the magnetostrictive film, wherein: a torque acting on the shaft calculated based on the detection results of the detection device; and the bias magnetization device applies a bias magnetic field to the shaft at a predetermined timing.
