A steering-shaft-rotation-angle detection device that detects a rotation angle of a steering shaft that is rotated by operation of a steering wheel, includes an electric motor that assists steering of the steering wheel by a driver, a speed reduction mechanism that reduces speed of rotation of the electric motor and transmits the rotation to the steering shaft, a rotating body that is attached to a rotation shaft of the electric motor, a signal output unit that outputs a signal in accordance with rotation of the rotating body, and a controller that calculates a rotation angle of the rotating body on the basis of the output signal from the signal output unit and calculates, on the basis of this rotation angle and a speed reduction ratio of the speed reduction mechanism, a rotation angle of the steering shaft.
