Abstract
A detection apparatus for detecting a feature portion of a composite member having a structure in which a first member having a separation layer inside is brought into tight contact with a second member. The composite member has, as the feature portion, a portion at which a peripheral edge of the first member projects outside a peripheral edge of the second member. The apparatus includes a shift detection section which detects a shift between the peripheral edge of the first member and the peripheral edge of the second member along an outer periphery of the composite member and a determination section which determines the feature portion on the basis of a detection result by the shift detection section.
