Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the consistent "seat" function by preventing occurrence of any "bottom-fall" deformation of a bottom wall located in a recessed manner in a container. SOLUTION: In a thick biaxial oriented blow-molded container 1, the bottom lower side 7 of a thick bottom wall 6 is formed in a triangular conical shape, and the wall thickness of a bottom wall center part 9 is formed to be smaller than that of a peripheral portion. Thus, the force to be applied to the bottom wall 6 caused by the effect of the heat accumulation is butted to the bottom wall center part 9 and canceled, and the heat effect itself of the heat accumulation is reduced to effectively prevent occurrence of any "bottom-fall" of the bottom wall 6.
