A rotation angle detection device includes a first detection unit, a second detection unit, and a calculation unit. The first detection unit detects a first rotation angle of a steering shaft that rotates with a steering wheel. The second detection unit detects a second rotation angle of a motor shaft coupled to the steering shaft via a speed reduction mechanism. The calculation unit receives the first rotation angle from the first detection unit and the second rotation angle from the second detection unit, and calculates the steering angle of the steering shaft based on a difference angle between the first rotation angle and the second rotation angle.
