This bottle is a tube-shaped bottle formed from a synthetic resin material and having a bottom. The bottom wall of the bottom has: a ground contact section which is located at the outer peripheral edge; a raised peripheral wall section which continues to the ground contact section from the inner side of the bottle with respect to the radial direction thereof and which extends upward; a movable wall section which protrudes from the upper end of the raised peripheral wall section toward the inner side of the bottle with respect to the radial direction thereof; and a depressed peripheral wall section which extends upward from the inner end of the movable wall section with respect to the radial direction of the bottle. The movable wall section is disposed so that the movable section can move upward together with the depressed peripheral wall section about the connection portion between the raised peripheral wall section and the movable wall section. An upwardly swollen section which is swollen upward is formed on the outer end of the movable wall section with respect to the radial direction of the bottle. |
