Zusammenfassung:This method for manufacturing a magnetostrictive torque sensor shaft 100 to which a sensor portion 2 of a magnetostrictive torque sensor 1 is to be attached includes: a heat treatment step of subjecting an iron-based shaft member to a carburizing, quenching, and tempering process; a shot peening step of performing shot peening using a steel shot media having a Vickers hardness at least equal to 1100 and at most equal to 1300, at least in a position on the shaft member, after the heat treatment step, to which the sensor portion 2 is to be attached; and a surface polishing step of subjecting the shaft member after the shot peening to surface polishing.
