Abstract
An inspection apparatus has: a gripping unit that grips a container filled with a liquid; a first lighting unit that emits light onto the liquid from one longitudinal end side of the container; and a second lighting unit that emits light onto the liquid from the other longitudinal end side of the container. The first lighting unit and the second lighting unit are arranged on a same side as an imaging device that acquires image data showing a state of the liquid as seen from the container, and are each installed so as to emit light onto the liquid from a position where a center axis passing through a center of the container is tilted by any angle of 0 degrees or more and 40 degrees or less.
