PROBLEM TO BE SOLVED: To provide a corrugated fiberboard tray which can be assembled from a small quantity of materials. SOLUTION: In the corrugated fiberboard tray, a pair of side walls 2 and a pair of end walls 3 are erected from the edges of a bottom plate 1 respectively, and a sash board 4 is extended from the upper edge of the end wall 3 so as to be engaged with the wall 2, thereby keeping the side wall 2 and the end wall 3 in an upright state. The side wall 2 is of a single construction and the opposite ends of the board 4 are placed on the upper edge of the wall 2, an engaging piece 6 projecting from the wall 2 is bent along a ruled line 7 and inserted into a hook-shaped insertion hole 8 provided in the board 4, and then the piece 6 is stretched. Since the side wall 2 has a single construction, consumption of material can be reduced, while the piece 6 is unremovably inserted into the hole 8, and hence the shape of the tray can be retained.
