Abstract
According to one embodiment, an inspection system for a secondary battery includes an image sensor, a detector, and an inspection processor. The image sensor captures an image of a fiber layer of an electrode structure of a secondary battery. The electrode structure includes an electrode and the fiber layer formed on a surface of the electrode. The electrode includes a current collector and an active material layer. The detector detects a color in data of the image captured with the image sensor. The inspection processor inspects a pinhole defect in the fiber layer based on the color detected with the detector.
