<p><P>PROBLEM TO BE SOLVED: To provide a pressure-resistant bottle capable of suppressing a swollen part formed on the outer circumferential surface of the bottle from being smooth by the internal pressure in the bottle. Ž<P>SOLUTION: In the pressure-resistant bottle 10, a mouth part 11, a shoulder part 12, a barrel part 13 and a bottom part 14 are integrated with each other using a synthetic resin, and a content for increasing the internal pressure in the bottle in a sealed state is filled therein. A plurality of quadrangular pyramidal swollen parts 19 swollen outwardly in the bottle radial direction are formed. In each swollen part 19, two of four corner parts 19b provided on a bottom part 19a square in side view of the bottle respectively constitute both axial O ends of the bottle in the swollen part 19, and the remaining two thereof respectively constitute both circumferential ends of the bottle in the swollen part 19. At least a part of the plurality of swollen parts 19 constitutes swollen zones A-G in which each swollen part 19 is connected over the entire circumference of the outer circumferential surface via the ends in each bottle circumferential direction.
