values of the surface irregularity enhanced image, and determining that among the potential recessed regions, a potential
recessed region located within a range of a predetermined distance from a location of the protruding region is not a recessed
region resulting from a bonding defect of the end portions of the sheet member, but a potential recessed region located out
of the range from the location of the protruding region is a recessed region resulting from the bonding defect, to detect
the bonding defect of the sheet member.
