PROBLEM TO BE SOLVED: To provide a method and device for inspecting cell clogging, with which a carrier having a plurality of tubular passages in the axial direction can be inspected efficiently for cell clogging. SOLUTION: In the method, the carrier 4, having a plurality of tubular passages in the axial direction, is inspected for clogging by cells by passing light rays through the passages. The method includes a projecting step of projecting the light rays emitted from a luminous surface which is wider than the diametral cross section of the carrier 4 and emits the light rays at uniform luminance from its whole surface upon one end face of the carrier 4, on which one openings of the tubular passages are opened and the light rays discharged from the other openings of the passages opened on the other end face of the carrier 4, after passing through the passages upon a projection plate 2 and an image observing step of observing the image projected upon the projection plate 2. Since the light rays emitted from the luminous surface are used, the tubular passages can be inspected at once for clogging by cells, and the cost for inspection can be reduced. |
