PROBLEM TO BE SOLVED: To improve the heat resisting, load bearing and forming characteristics of a bottom and to surely control the deformation of its recess and ground contact part as to a bottle which has a bottom provided with a recess the outer periphery of which is provided with a ground contact part.SOLUTION: This tubular bottomed bottle has a recess 6 on the bottom face center of the bottom 3 formed in the bottom end of a tubular body, and the outer periphery of the recess 6 is provided with an annular ground contact part 7. A ridgeline part 71 which is roughly polygonal in planar view is formed between the recess 6 and the part 7. The recess 6 is provided with: in planar view, a plurality of receding line parts 61 which are arranged radially with the bottle axis line O as the center and extended in the diameter direction toward the corner 70 of the part 71; and a plurality of flat face parts 60 adjacently provided peripherally through the parts 61. |
