A folding container comprising: an upper frame having two pairs of opposing frame portions each having an engagement portion; a bottom frame with a closed end and having opposing frame portions which respectively correspond to those of the upper frame, each frame portion of the bottom frame having a pivotally support portion; two side plates pivotally supported at their lower end portions by the pivotally support portions, respectively, which are formed on one of the two pairs of frame portions of the bottom frame so that the side plates are able to pivot upward, each side plate being slidably supported at both lateral end portions thereof by the upper frame, the upper end portions of the side plates being engaged with the respective engagement portions formed on one of the two pairs of frame portions of the upper frame; and two end plates pivotally supported at their lower end portions by the pivotally support portions, respectively, which are formed on the other pair of frame portions of the bottom frame, the upper end portions of the end plates being engaged with the respective engagement portions formed on the other pair of frame portions of the upper frame. Accordingly, it is possible to readily assemble and fold the container and also possible to reduce the thickness of the container when folded.
