PROBLEM TO BE SOLVED: To provide a visual inspection apparatus capable of reducing the possibility of incorrect decision of defective items of objects to be inspected as nondefective items. SOLUTION: The visual inspection apparatus (1) includes an imaging unit (3) for acquiring inspection images acquired by photographing an object to be inspected; a feature value extraction unit (51) for extracting feature value on the object to be inspected from the inspection images; and a quality decision unit (54) for determining the quality of the object to be inspected by input of the feature value to a discriminator constituted as a support vector machine. The boundary of a region of defective-item feature value is corrected such that the region of the defective-item feature value, a region containing feature value extracted from the object to be inspected determined as a defective item by the discriminator, may be larger than a region of defective-item characteristic region determined by the learning of the support vector machine.
