PROBLEM TO BE SOLVED: To increase the degree of freedom in design, and at the same time, make the deformation of a bottle less outstanding even when the internal pressure decreases by forming an uneven pattern for which a large number of recessed parts and protruding parts are arranged at random, on the almost total area of the body part of a plastic bottle. SOLUTION: An uneven pattern 2 for which a large number of protruding parts 21 and recessed parts 22 are arranged at random, is formed on the almost total area of the body part 13 of a plastic bottle 1. Or, an uneven pattern for which a large number of thin and long protruding parts and thin and long recessed parts are arranged in an orientation in the longitudinal direction, is formed. Or, an uneven pattern for which a large number of independent protruding parts being surrounded by a recessed part, or independent recessed parts being surrounded by a protruding part, are arranged, is formed. The uneven pattern 2 may occupy one half or more of the surface area of the body part 13, and the uneven pattern is formed into a comparatively fine pattern of such a degree wherein the number of peaks of the protruding parts 21, or the number of bottoms of the recessed parts 22 are evenly formed by, e.g. 2-15 peices for every 1cm length on the cut surface.
