An electric power steering device is provided. The electric power steering device dampens vibration to improve response characteristics by using velocity I-P control in a vehicle having functions of automatic steering control and manual steering control, and has control performance resistant to external disturbances such as changes in the road surface. The electric power steering device is provided with a steering angle control unit and a switching unit. The steering angle control unit, during automatic steering control, calculates a motor current command value such that the actual steering angle approaches the target steering angle. The switching unit inputs a first motor current command value and a second motor current command value, and switches between the first motor current command value and the second motor current command value according to a switching signal. The steering angle control unit is configured to comprise a rate limiter which smoothes the target steering angle and to output a motor current command value on the basis of the deviation between the output of the rate limiter and the actual steering angle, and the motor angular velocity.
