A low-cost magnetostrictive torque sensor having a high sensitivity is obtained. A torque sensor 10 includes a substrate 12, a magnetostrictive portion 26, a magnetostrictive portion 28, a detection coil 18a, a detection coil 18b, a detection circuit 48, and a detection circuit 50. The substrate 12 has a tubular shape. Each of the magnetostrictive portions 26 and 28 is constituted by a plating film and disposed on the outer peripheral surface of the substrate 12. The detection coil 18a generates a magnetic flux passing through the magnetostrictive portion 26. The detection coil 18b generates a magnetic flux passing through the magnetostrictive portion 28. Each of the detection circuits 48 and 50 detects a potential between the detection coil 18a and the detection coil 18b.
