Provided is a sensor device that is machinable and mountable easily. A sensor device includes an external gear configured to rotate together with a pinion shaft, driven gears configured to rotate by meshing with the external gear, permanent magnets configured to rotate together with the driven gears, magnetic sensors configured to detect magnetic fields of the permanent magnets, a circuit board assembly having the magnetic sensors mounted on a printed circuit board, a tubular first housing member that houses the external gear, and a second housing member that supports the driven gears and houses the circuit board assembly. The second housing member has a flange portion that abuts against an open end face of a fitting hole of the first housing member, and parts of the driven gears that protrude from the flange portion mesh with the external gear inside the first housing member.
