PROBLEM TO BE SOLVED: To provide a resin container where deformation such as sink is hardly generated against impact and a load applied to a side surface of the container, and which can be lighter in weight.SOLUTION: A resin container includes: a mouth part where a cap is freely attachable and detachable; a shoulder part connected with the mouth part; a body connected with the shoulder part; and a bottom part connected with the body and located on the lowest section. In the resin container, a plurality of corrugated recesses 11, 12 and 13, the cross sectional shapes of which are formed into corrugated circumference shapes when first protruding regions 14 and second protruding regions 15 are alternately arranged in a circumferential direction are provided in a vertical direction of the body. In this case, the corrugated recesses include: the first protruding regions 14 protruding inward in a radial direction of the body; and the second protruding regions 15 protruding more inward in the radial direction than the first protruding regions 14 into mountain shapes. |
