description Provided are a magnetostrictive torque sensor shaft with excellent processing accuracy and stability of quality and a preferred method for manufacturing the shaft. The magnetostrictive torque sensor shaft has an amorphous thermal spray coating on the surface of a substrate made of a metal material, the amorphous thermal spray coating having a magnetostrictive property and being formed by thermal spraying, and the substrate surface being subjected to surface roughening by laser irradiation. The laser irradiation is performed in the surface roughening process prior to the amorphous thermal spraying and in pattern formation process after the thermal spraying.
