PROBLEM TO BE SOLVED: To provide an electrically-driven working machine with excellent workability, which can stably continue work even if a remaining battery capacity is reduced to a low-consumption area from a normal state during the work. SOLUTION: Even if the remaining capacity of a battery 20 falls short of a threshold value during the driving of an actuator, the maximum output of the actuator is kept at a high value until the driving of the actuator is stopped, and limited to a low value after the driving of the actuator is stopped. Since the maximum output of the actuator is not abruptly limited to the low value during the work performed by driving the actuator, the work can be stably performed, and a sense of discomfort given to a driver can be eliminated or relaxed.
