Zusammenfassung:PROBLEM TO BE SOLVED: To provide an electric power tool that enables a stopper fastening operation to be reliably performed without use of a torque sensor.SOLUTION: An electron pulse driver 1 includes a motor 3 that can run in a normal rotation direction or a reverse rotation direction, a hammer 42, and an anvil 52 that is struck with a hammer 42. The electron pulse driver 1 continues drive of the motor 3 in the case where an electric current of the motor 3 when the motor 3 runs in the reverse rotation direction exceeds an electric current of the motor 3 during the previous reverse rotation of the motor 3.
