PROBLEM TO BE SOLVED: To provide a case having a hexagonal bottom in which the bottom surface hardly falls out. SOLUTION: The case having a hexagonal bottom 1 has a lower opening portion having a hexagonal shape having first to sixth lower sides in plan view, a foldable cylindrical peripheral wall 2, and the bottom surface 5 closing the lower opening portion. The bottom surface 5 has a right side flap piece 6, a left side flap piece 7, and a center flap piece 8. A center bending ruled line 8a parallel to the third lower side is formed at the central part of the surface of the center flap piece 8, and a right side bending ruled line 6a and a left side bending ruled line 7a are respectively formed along an extending line of the center bending ruled line 8a on the surfaces of the right side flap piece 6 and the left side flap piece 7. The center flap piece 8 can be bent only inward toward the peripheral wall 2 on the center bending ruled line 8a, and the center flap piece 8 is arranged below the right side flap piece 6 and the left side flap piece 7.
