PROBLEM TO BE SOLVED: To provide an electrically-driven working machine with excellent reliability, which can increase the amount of work and a period of operating time by effectively utilizing a limited battery capacity. SOLUTION: This electrically-driven working machine is equipped with electric motors 103 and 106 which serve as main power sources for an actuator, and a battery 20 which serves as a driving power source for the electric motors 103 and 106. The electrically-driven working machine, which is equipped with a control unit 100, measures a battery voltage of the battery 20, determines the remaining capacity of the battery 20 from the measured battery voltage, and changes the maximum output of the actuator depending on the result of the determination of the remaining capacity of the battery.
