This bottle (1) is configured in such a manner that the tube-shaped body (13) thereof has formed thereon panels (51) which are arranged at intervals in the circumferential direction and which are recessed inward in the radial direction of the body (13), and that columns (52) are provided between the panels (51) adjacent to each other in the circumferential direction. Each of the panels (51) has a panel bottom wall (53) located on the inside in the radial direction, and also has side walls (54) extending outward in the radial direction from the outer peripheral edges of the panel bottom wall (53). A rib (55) protruding outward in the radial direction is formed on each of the panel bottom walls (53) in such a manner that the rib (55) is located between the vertical side walls (54a) of the side walls (54) so as to be separated from the vertical side walls (54a), the vertical side walls (54a) facing at least the circumferential direction. |
