PROBLEM TO BE SOLVED: To provide an inspection method for a container that can inspect the same portion of a container with a plurality of imaging cameras of different inspection wavelengths and lens types, without a wide inspection space. SOLUTION: The plurality of imaging cameras 2 to 4 of different inspection wavelengths and lens characteristics are arranged on one side of a container, and illuminating means 8 are arranged on the other side of the container. The illuminating means 8 emit a light beam containing inspection wavelengths necessary to the imaging cameras 2 to 4. The light beam transmitted through the same portion of the container is distributed by half mirrors 5 and 6 as distributive optical means among the imaging cameras 2 to 4, which simultaneously perform a plurality of types of inspections including a visual inspection and a strain inspection.
