PROBLEM TO BE SOLVED: To provide a rectangular parallelopiped-like case at a low cost, which is formed from hollow resin plates and which prevents side plates from being deformed to swell without mounting a reinforcing member. SOLUTION: A rectangular parallelopiped-like case 2 comprises long side plates 4, 5, short side plates 6, 7, bonding side plates 8a, 8b, 9a, 9b and a bottom plate 10, and folding lines 15a-15h are formed on the mutual boundaries among the respective plates. Each of the folding lines 15a, 15b provided on the boundary between the bottom plate 10 and the long side plate 4 and between the bottom plate 10 and the long side plate 5, respectively, from among the folding lines 15a-15h, are formed into a curved line curved inside. By curving the folding lines 15a, 15b inside, the long side plates 4, 5 are put into a slightly curved state toward the inside of the rectangular parallelopiped-like case and do not swell outward. As a result, the rectangular parallelopiped-like case is not caused to swell outward even without mounting a reinforcing frame, an auxiliary plate or the like. Further, since it is unnecessary to use a reinforcing frame, an auxiliary plate or the like, a rectangular parallelopiped-like case can be manufactured at a low cost in a simple precess.
