A work machine includes: hydraulic actuators 21, 22, 23, 31, and 32; a capacitor 61 for storing electric power when a generator motor 44 operates as a generator and for supplying electric power when the generator motor 44 operates as a motor; and a swing electric motor 10, the hydraulic actuators 21, 22, 23, 31, and 32 and the swing electric motor 10 are operated by operation of operating levers 50, 70. The work machine includes an idling stop control unit 110 for stopping the idling of an engine 40 and retains the swing electric motor 10 in an operation prohibited state at least on the condition that stored voltage of the capacitor 61 is predetermined voltage or higher when the neutral states of the operating levers 50, 70 continue for a predetermined stop time during operation of the engine 40.
