PROBLEM TO BE SOLVED: To provide an electric power steering device of which the structure is simplified by storing each electronic apparatus in an integrally formed housing part. SOLUTION: The electric power steering device is equipped with a first housing and a second housing. The first housing has a gear housing part having a through-hole passing through an input shaft and an opening part provided at the axial direction opposite side of the through-hole, a motor housing part integrally provided on the gear housing part, and a power system substrate housing part integrally provided with the gear housing. The second housing houses an electric motor housed in the motor housing part, a power system substrate which is housed in the power system substrate housing part and drive-controls the electric motor, a control system substrate which is housed in the first housing, and outputs the control signal to the power system substrate based on the steering torque signal from a torque sensor, houses an output shaft, and closes the opening part of the first housing.
