[Problem] To provide a torque sensor which is improved with regard to the torque detection characteristic, manufacturing cost, and the like, and a manufacturing method therefor. [Solution] This torque sensor comprises a magnetostrictive section containing an amorphous alloy film (including a metallic glass film) formed on a surface of a rotation shaft. The amorphous alloy film in the magnetostrictive section is formed on the surface of the rotation shaft by means of thermal spray wherein a metallic powder is melted by spraying flame containing the metallic powder, and the flame is cooled by a cooling gas from the outside before the flame reaches the surface of the rotation shaft. |
