A power feed system of an electrically driven construction machine that can enhance the work efficiency of the electrically driven construction machine while preventing damage to a power feed cable is provided. The power feed system includes a cable drum from and by which the power feed cable from an external power supply is drawn out and wound up, a drum sensor, a rotation angle sensor that senses the routing direction of the power feed cable with respect to an electrically driven excavator, a monitor, and a controller. The controller computes the wound-up length of the power feed cable wound up by the cable drum on the basis of the rotation amount of the cable drum sensed by the drum sensor and causes the monitor to simultaneously display this wound-up length and the routing direction sensed by the rotation angle sensor.
