PROBLEM TO BE SOLVED: To provide double folding doors which can be readily opened and closed, even by a physically challenged, and which can be fully opened to either side, even when a door attachment door stop is provided. SOLUTION: The double-folding doors include a door end-side door body 111, and a door tail-side door body 112, which is turnably connected to the door body 111 adjacently thereto. A width-direction dimension B of the door tail-side door body 112 is set smaller than 1/2 the width-direction dimension of the door end-side door body 111. In other words, in the door end-side door body 111, the width-direction dimension A of the door end-side portion with respect to a rotating shaft portion 131, supported near the width-direction center of the door body 111, is set larger than the width-direction dimension (=B) of the door tail-side portion, with respect to the rotating shaft portion 131. As a result, even a physically challenged is able to fully open the door with ease, when a handle portion 111a of the door end-side door body 111 has only to be pushed with a weak force; and the door can be opened completely and fully, when the door is opened to either of the sides even in the case where the door attachment door stop 210 is provided.
