Summary:PROBLEM TO BE SOLVED: To inspect a joint part having dispersion in surface roughness or jointing shape, with accuracy. SOLUTION: A plurality of images of a jointing part 4a are obtained by irradiating the joint part 4a with light, while changing the irradiation direction and the irradiation quantity of light, and a plurality of the photographed images are compared to each other so as to select and sort an image having the edge image of the jointing part 4a imaged most clearly, and the quality of the jointing part 4a is decided by using the sorted image.
