PROBLEM TO BE SOLVED: To provide an inspection device capable of inspecting a container packaged with a heat-shrinkable label. SOLUTION: The inspection device comprises a conveyor for conveying a container filled with a liquid, a plurality of microwave sensors, and a determination apparatus. The microwave sensor projects the microwave to the container conveyed by the conveyor, and receives the microwave transmitted through the container. The determination apparatus determines the filling state of the liquid in the container from the result of measurement by the plurality of microwave sensors, and transmits the signal when determining that the filling state of the liquid is abnormal. The container is packaged with a heat-shrinkable label, and the plurality of microwave sensors are arranged so as to project the microwave to the positions of different heights of the container.
