The invention provides a safety device of an elevator, capable of detecting a rope-shaped foreign matter and a belt-shaped foreign matter with little diameter and reducing the repair and maintenance operation intensity and making the passenger quickly clear the foreign matter without effecting the appearance shape and when detecting the foreign matter. The safety device. The safety device of the elevator comprises lighting devices (8) arranged between an elevator door (1) at the elevator car side and its door sill (2) and between an elevator door (1) at the hall side and its door sill and capable of linearly lighting on the whole front-surface width of the elevator access door, a camera (10) arranged on the upper part of the elevator access door and an image processing unit (11) for processing the image obtained by the camera, in the safety device, the lighting device lights and the camera obtains the image on the door sill surface and the front end surface of the elevator door and the image processing unit extracts the area lighted by the lighting device and the presence of the foreign matter is detected based on whether the lighted area is separated or not.
