PROBLEM TO BE SOLVED: To provide a control technology for an electric working machine, driving an electric motor only by a clear operation procedure, and to provide an electric working machine which adopts the technique. SOLUTION: The controller includes a battery unit for feeding power to an electric motor for transmitting power to a working unit through a power feeder wire, a power supply switch disposed on the power feeder, and a motor power supply control portion for controlling the power supply switch. The motor electricity supply control portion has a preferential signal evaluation portion which sets a negligible state for reserving a start control for the electric motor on the basis of an ON state signal from a sub-switch in the OFF state of a main switch, and cancels the negligible state by an OFF state signal from the sub-switch, and outputs, to the power-feeding switch, a control signal enabling to close power supply switch to feed power to the electric motor, when the ON states of both the main switch and the sub-switch is confirmed, when the negligible state is not set.
