An electronic door lock apparatus is provided to reduce installation cost by using a mechanical door lock that has been installed on a door. An inner body(200) is installed on an inner of a door and contains a battery. An outer body(300) is installed on an external of the door and provided with a keypad(301) for opening the door on a front of the outer body(300). A control circuit is provided inside of the inner body(200) to control an operation of a locking member(102). A driving motor is provided inside the inner body(200) to be driven forwardly and backwardly by the control circuit. A decelerator is provided inside the inner body(200) to reduce rotatory force of the driving motor. A rotatory force transmitter is interlocked with the decelerator and axis-coupled to a locking member operation unit(103) to transmit the rotatory force of the decelerator to the locking member operation unit(103).
