A bottle that is formed from a synthetic resin material in a cylindrical shape having a bottle axis and a bottom at one end, comprising: a plurality of circumferential grooves that extend continuously around the entire circumference of a body portion and are formed at a distance from each other in a vertical direction along the bottle axis around the entire circumference of the body portion, the plurality of circumferential grooves extend cyclically in a circumferential direction while undulating up and down in the vertical direction when viewed from the side of the body portion so as to form a wave pattern, the plurality of circumferential grooves are formed such that phases of any two circumferential grooves thereof adjacent to each other in the vertical direction are offset from each other, the plurality of circumferential grooves are formed such that, of any two circumferential grooves thereof adjacent to each other in the vertical direction, apex portions (15a, 15b) of a first circumferential groove are respectively located in an area in the circumferential direction where intermediate portions located between adjacent apex portions (15a, 15b) of a second circumferential groove are positioned, upper apex portions forming upwardly protruding curves and lower apex portions forming downwardly protruding curves serve as the apex portions (15a, 15b) of the first and second circumferential grooves, characterized in that the plurality of circumferential grooves are formed such that, of any two circumferential grooves thereof adjacent to each other in the vertical direction, a first area, from a position in the vertical direction where the upper apex portions of the first circumferential groove are located to a position in the vertical direction where the lower apex portions of the first circumferential groove are located, does not overlap with a second area, from a position in the vertical direction where the upper apex portions of the second circumferential groove are located to a position in the vertical direction where the lower apex portions of the second circumferential groove are located, in the vertical direction around the entire circumference of the body portion. a plurality of circumferential grooves that extend continuously around the entire circumference of a body portion and are formed at a distance from each other in a vertical direction along the bottle axis around the entire circumference of the body portion, the plurality of circumferential grooves extend cyclically in a circumferential direction while undulating up and down in the vertical direction when viewed from the side of the body portion so as to form a wave pattern, the plurality of circumferential grooves are formed such that phases of any two circumferential grooves thereof adjacent to each other in the vertical direction are offset from each other, the plurality of circumferential grooves are formed such that, of any two circumferential grooves thereof adjacent to each other in the vertical direction, apex portions (15a, 15b) of a first circumferential groove are respectively located in an area in the circumferential direction where intermediate portions located between adjacent apex portions (15a, 15b) of a second circumferential groove are positioned, upper apex portions forming upwardly protruding curves and lower apex portions forming downwardly protruding curves serve as the apex portions (15a, 15b) of the first and second circumferential grooves, characterized in that the plurality of circumferential grooves are formed such that, of any two circumferential grooves thereof adjacent to each other in the vertical direction, a first area, from a position in the vertical direction where the upper apex portions of the first circumferential groove are located to a position in the vertical direction where the lower apex portions of the first circumferential groove are located, does not overlap with a second area, from a position in the vertical direction where the upper apex portions of the second circumferential groove are located to a position in the vertical direction where the lower apex portions of the second circumferential groove are located, in the vertical direction around the entire circumference of the body portion.
