ものが知られている。2. Description of the Related Art Conventionally, in manufacturing a sealed battery, for example, a group of electrodes is housed inside a battery case composed of one cell chamber that houses one group of plates (cells). After a sealant is applied in a ring shape to a square or circular annular lid mounting portion so as to surround the opening of the container, a battery case lid is provided, and the battery is sealed by welding, caulking, etc. to produce a sealed battery. However, if the application state of the annular sealant application portion is poor and there is a discontinuous portion where the sealant is not applied to the sealant application portion, the electrolytic solution may be discharged through the discontinuous portion after the sealed battery is assembled. Leakage inconvenience occurs. Therefore, before the lid is applied to the battery case, it is necessary to determine whether or not the applied state of the sealant applied portion is good. As a conventional method and apparatus for judging the quality of application of a sealant application section, for example, as disclosed in Japanese Patent Application Laid-Open No. 3-37955, a sealant application section is photographed with a camera, and the image signal is sent to an inspection device. In the inspection device, image processing is performed to compare the area of the part where the sealant is applied and the area where the sealant is not applied within a predetermined range with the area under the normal state, and the image is different from the normal state by a certain degree or more. If it is determined that the product is defective, it is known that the product is discharged as a defective product.

In the case of comparing and judging the quality, depending on the image processing, even if there is a discontinuous portion 48 in the minute sealant applying portion 13 as shown in FIG. 11, the discontinuous portion has a small area. In such a case, since the difference value is extremely small in the area difference calculation, there is a tendency that the battery is erroneously determined as a non-defective product.
