PROBLEM TO BE SOLVED: To provide an inspection device capable of inspecting a state of the lower portion of a container packaged with a heat-shrinkable label. SOLUTION: The inspection device comprises a detector 5 which projects light beams on a lower part of a container packaged with a heat-shrinkable film and receives the light reflected by the lower part of the container, and a determination apparatus 6 for determining presence/absence of any heat-shrinkable film on the lower part of the container based on the output of the detector. The detector includes a plurality of sensors to detect presence/absence of any heat-shrinkable film at a plurality of parts located at substantially the same level of the lower part of the container. The lower part of the container to be detected by the detector is preferably set to be higher than the lower limit height position in a range of the height position at which the heat-shrinkable film is packaged.
