The invention provides a door opening and closing detection system of an elevator, which improves the detection precision of door opening and closing of the elevator. A door opening/closing detection system is provided with a magnetic sensor provided in an elevator car, and an opening/closing detection device for detecting the opening/closing of a metal landing door on the basis of whether or not the difference between values measured by the magnetic sensor in a time interval exceeds a threshold value. A magnet is provided in the landing door or in the vicinity of the landing door.
