Abstract
A low-cost magnetostrictive torque sensor having a high sensitivity is obtained. A torque sensorincludes a substratea magnetostrictive portiona magnetostrictive portiona detection coila detection coila detection circuitand a detection circuitThe substratehas a tubular shape. Each of the magnetostrictive portionsandis constituted by a plating film and disposed on the outer peripheral surface of the substrateThe detection coilgenerates a magnetic flux passing through the magnetostrictive portionThe detection coilgenerates a magnetic flux passing through the magnetostrictive portionEach of the detection circuitsanddetects a potential between the detection coiland the detection coil
