An electromotive tool includes a housing, a motor, an electric control device, and a circuit device connected to the electric control device in a parallel manner. The electric control device includes a battery set. The circuit device includes an electric double layer capacitor connected to the battery set of the electric control device in a parallel manner. Thus, the electric double layer capacitor supplies a relatively higher electric current to the motor so that the output shaft of the motor produces a relatively higher torque instantaneously.
