Abstract
The present invention provides a transparent liquid inspection apparatus capable of identifying a boundary between a transparent liquid applied on a base material which provides a multi-piece product and the base material, and automatically inspecting an applied condition of the transparent liquid without influence of a background of the base material. A projected image of an illumination source (2) is reflected on a surface of the transparent liquid as a mirror, the projected image is picked up by cameras (41 to 44), and the image is analyzed by an image processing unit (8), thereby inspecting an amount of displacement of the transparent liquid from a predetermined application position and expansion of the surface of the transparent liquid.
