A magnetostrictive torque sensor incorporated in an electric power steering apparatus includes first through fourth detection coils, which are disposed face-to-face with a magnetostrictive film across a bobbin winding holder that is disposed around an outer circumferential surface of the magnetostrictive film. A bobbin support, which supports the bobbin winding holder, is disposed on the bobbin winding holder at a central position in the axial direction of the first through fourth detection coils.
