<p>A method for manufacturing a magnetostrictive torque sensor compriseis the steps of forming magnetostrictive films (14A, 14B) on a rotating shaft (11) of a magnetostrictive torque sensor (10), creating magnetic anisotropy in the magnetostrictive films (14A, 14B) formed in the magnetostrictive film formation step (P1), and demagnetizing the rotating shaft (11). The demagnetization step (P32) is provided in any of the stages after the magnetostrictive film formation step (P1), and comprises initiahzing the remanent magnetism (MS, MK) created in the rotating shaft (11).</p> |
