Abstract
An inspection method for determining a presence of a defect on a sides surface of a pillar-shaped honeycomb structure including generating strip-shaped images by repeatedly capturing the side surface part by part with an area camera while relatively moving the area camera with respect to the pillar-shaped honeycomb structure; determining the presence or absence of defects based on the strip-shaped images when a number of the strip-shaped images generated is sufficient to cover the entire side surface; a shutter speed when the area camera captures a part of the side surface for generating a single strip-shaped image is 10 to 1000 μsec; and each of the strip-shaped images has a length covering the entire height of the pillar-shaped honeycomb structure in a longitudinal direction, and a length of 1 to 10 mm in a width direction.
