PROBLEM TO BE SOLVED: To provide a torque sensor for improving torque detection accuracy and reducing manufacturing cost. SOLUTION: A torque is detected based on the change in magnetic resistance in a magnetic circuit. At least one of the components of the magnetic circuit is molded of a magnetic resin material that is composed by dispersing magnetic powder to a base material 200 made of a synthetic resin. The magnetic powder dispersed into the base material 200 includes a large-diameter particle 201 indicating soft magnetism and a small-diameter particle 202 indicating paramagnetism whose diameter is smaller than the large-diameter particle 201. |
