摘要： PROBLEM TO BE SOLVED: To provide a magnetostrictive torque sensor capable of suppressing deterioration in detection accuracy.SOLUTION: A magnetostrictive torque sensor 41 comprises: a rotation shaft 24 having a magnetostrictive part such as a magnetostrictive film 82; and coils such as detection coils 85, 85 for detecting changes in magnetic characteristics such as magnetic permeability of a magnetostrictive film 81. The rotation shaft 24 further includes an extension part 24e that is separate from the magnetostrictive part on the side of a shaft end part such as a connection part 24i of the rotation shaft 24. A cross-sectional area of a part of the rotation shaft 24, having the extension part 24e is larger than a cross-sectional area of a part of the rotation shaft 24 interposed between the extension part 24e and the magnetostrictive part 82, on a flat surface vertical to a central axis CL of the rotation shaft 24. The rotation shaft 24 itself and the extension part 24e are made of a magnetic material. Further, the magnetostrictive torque sensor 41 preferably comprises a magnetic shield 54a opposing the extension part 24e.
