Provided is a torque sensor (TS1) comprising: a magnetic member (20) that is fixed to a first output shaft (3); a pair of first and second yoke members (31, 32) that are fixed to an input shaft (1) so as to surround the outer peripheral side of the magnetic member (20); and a magnetic sensor (60) that detects magnetic flux spanning the interval between the yoke members (31, 32). The magnetic member (20) is configured from: a sleeve (23) formed from a metal material, having a substantially cylindrical shape, and comprising a plurality of support sections (26) that extend along the radial direction of the axial end edge of said sleeve (23) and an engagement protrusion (27) that extends along the axial direction in the peripheral interval between each of the support sections (26); and an annular permanent magnet (21) having notched therein a plurality of engagement grooves (24) that pass through the inner peripheral surface of said permanent magnet (21) in the axial direction. In addition, the permanent magnet (21) and the sleeve (23) are joined using a resin-based filler material (22) that is provided so as to span the interval therebetween.
