Abstract
There is disclosed a torque sensor comprising: a shaft whose torque is to be detected; a magnetostrictive film formed on the shaft; and a coil for detecting a change of a magnetic property of the magnetostrictive film, wherein an intermediate film having a melting point lower than a melting point of the shaft and a melting point of magnetostrictive film is formed between the shaft and the magnetostrictive film, so that the torque sensor is superior in productivity and durability and can detect a torque in a rotational direction.
