[PROBLEM] To provide a novel inspection method and system of a container enabling inspection of excess entrainment of air inside a flexible container and inspection of seal defects of a flexible container to be performed by a single technique simultaneously, enabling a full run of flexible containers to be continuously inspected on the production line, and giving a high inspection precision. [MEANS FOR SOLUTION] Inspecting for seal defects of a container and excess entrainment of air in a container in an inspected object comprised of a flexible container in which a liquid is filled, during which placing the inspected object in an air-tight container, sucking out the air in the air-tight container to reduce the pressure sufficient to make container outer walls of the inspected object expand, measuring an expansion dimension of the container outer walls, and comparing it with a preset threshold value to judge the quality of the inspected object.
