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.
