A rotation angle detection device that detects a rotation angle of a valve body. The rotation angle detection device includes a shaft, a gear, a magnetic field generator, and a magnetic detection element. The shaft is connected to the valve body. The magnetic field generator is arranged on a gear side and generates a magnetic field. The magnetic detection element is arranged on an extension of the shaft and detects magnetic flux density of the magnetic field that rotates together with the gear.
