A foldable container comprises rotatably mounted side plates on the long sides of a bottom plate that opposed to each other and rotatably mounted side plates on the short sides of the bottom plate that also opposed each other. The foldable container is folded by folding down the pair of the short side side plates onto the pair of the long side side plates. The foldable container is assembled in the form of a box by raising the pair of short side side plates and then raising the pair of long side side plates. Both edge portions on the inner face of each raised short side side plate are supported by the long side side plate edge faces. A supporting protrusion is provided on edge portion of the inner face of the short side side plate. When the short side side plates are folded down, the supporting protrusions on each edge portion is fitted into concave portions provided in each long side edge portion of the bottom plate.
