An inspection method of a honeycomb structure comprises the steps of illuminating one end face 15 of a honeycomb structure 11 as an inspection target by a light source 1; condensing, by a condensing lens 2 as a lens having an angle of view, light which is emitted from the light source 1 to the one end face 15, passed through cells of the honeycomb structure 11 and radiated from the other end face 16; receiving the light condensed on the condensing lens 2 by a camera 3; subjecting the light received by the camera 3 to image processing by an image processor 4, thereby specifying the radiated position of the light on the other end face 16; and calculating the tilt of the cells 14 of the honeycomb structure 11 from the radiated position of the light on the other end face 16, and the direction of the tilt.
