[PROBLEMS] A resin container that is less likely to have damage such as deformation at its bottom corner even if it is dropped or collides with another object and that can be reduced in thickness. [MEANS FOR SOLVING PROBLEMS] The resin container has side walls (20) extending in the vertical direction and a bottom wall (40) closing the bottom of the container. Lower ribs (74) continuously circumferentially extending along a bottom wall edge section are formed at the lower part of the container. The lower ribs (74) formed at the lower parts of the side walls so as to be contiguous to the bottom wall (40) and to form a wave form in a cross section taken in the vertical direction of the container.
