PROBLEM TO BE SOLVED: To provide a tray capable of improving a support strength of overlapping, and producible at a low cost, and a method for manufacturing the same.SOLUTION: A folding part 3 is folded and overlapped on an overlapping part 5, and another tray is overlapped on the overlapping part 5 so as to support the other tray on the upper side by the overlapping part 5 reinforced by the folding part 3, and improve a support strength of overlapping. It is possible to improve the support strength of the overlapping part 5 also by forming the whole of a tray 1 in a nearly equal thickness by vacuum molding, and to produce the tray at a low cost. |
