<P>PROBLEM TO BE SOLVED: To provide a chromatographic inspection apparatus for detecting and accurately correcting coloration unevenness of a coloration area of a chromatographic test piece. Ž<P>SOLUTION: The chromatographic inspection apparatus reads scattered reflected light from the chromatographic test piece 5 by an imaging element 16 in an imaging optical system 17 arranged to have an inclination angle θ with respect to the chromatographic test piece 5. A prism 12 is disposed on the incident side of a condensing lens 13 and an imaging lens 14 for forming an image on the imaging element 16, and a wedge angle and an arrangement rotation angle of the prism 12 are set corresponding to the inclination angle θ to correct the optical path length difference of the imaging optical system in the coloration area 11 and to detect and accurately correct the coloration unevenness of the coloration area 11.
