The hinged door is rotatably installed on the door frame using a hinge or the like. The sliding door is installed on the door frame so that it can move in a straight line using rails.

Since the conventional casement door is rotatably installed on the door frame, it is difficult to utilize a space equivalent to the rotational trajectory of the casement door. In addition, since the door frame of the sliding door is formed to be twice as long as the width direction of the sliding door, a separate space for installing the sliding door is required. Accordingly, a door capable of improving space utilization is required.

In order to supplement this point, a composite door in which a sliding door and a sliding door are combined as in Patent Document 1 has been developed and applied.
