A method for inspecting inferiority in shape of an object is provided, which is accomplished through an inspection image obtained from an inspection object. The object shape inferiority inspection method includes the steps of: preparing at least one reference image for judgement as to shape inferiority in the inspection object considering an allowable error for shape; obtaining the inspection image from the inspection object; comparing grayscales of each one part, at least, of portions where the reference image and the inspection image mutually correspond, and judging whether inferiority in shape of the inspection object exists, based on the result of the grayscale comparison. Accordingly, the time required for inspecting inferiority in shape of an object could be greatly reduced and shape inferiority over the entire area of an object can be detected.
