In an inspection method for a honeycomb structure in which multiple through-holes are placed substantially parallel in a top surface and bottom surface, the following are contained: a shining step in which light is shone on the front surface of the honeycomb structure while scanning said front surface; a light-receiving step in which reflected light of the light shone on the honeycomb structure in the shining step is received; and a computation step in which shape data related to the shape of the honeycomb structure is computed. Said shape data is computed from the relationship between: the shining angle of the shining light that was shone on the honeycomb structure in the shining step; and the light-receiving angle of the reflected light that was received in the light receiving step.
