PROBLEM TO BE SOLVED: To suppress an increase in the number of components and an increase in assembly man-hours in a torque/steering angle sensor which makes it possible to detect a steering torque and a steering angle.SOLUTION: A torque/steering angle sensor 2 comprises: a ring magnet 31 that rotates together with a first rotary member 111 and in which a plurality of magnetic poles are formed in the circumferential direction; first and second magnetic yokes 41, 42 whose relative physical relationships with the magnetic poles of the ring magnet 31 changes in accordance with the torsion of a torsion bar 113; first and second annular magnetic flux collection ring 51, 52, each magnetically coupled to the first and second magnetic yokes 41, 42; a first magnetism detection element 61 for detecting the intensity of a magnetic field between the first and second magnetic flux collection ring 51, 52; a second magnetism detection element 62 for detecting the intensity of a magnetic field that changes with the rotation of the ring magnet 31; and a circuit board 63 on the packaging surface 63a of which the first magnetism detection element 61 and second magnetism detection element 62 are packaged, the circuit board 63 being disposed in such a way that the packaging surface 63a is along a direction parallel to an axis of rotation O.SELECTED DRAWING: Figure 3 |
