Abstract
A detection method in which light is irradiated on a bagged electrode, and an electrode is disposed inside of a bag-shaped separator for detecting breakage of the separator, the method includes capturing an image by irradiating the light onto the bagged electrode so that a first portion in which the light has been transmitted through n layers of the separator, and a second portion in which the light has been transmitted through equal to or less than n−1 layers of the separator, will have mutually different brightness levels, while capturing an image of the bagged electrode, detecting the first portion from the brightness of the image that is obtained by capturing the bagged electrode, and determining a breakage of the separator, based on the distance between edges of the first portion, and of an electrode portion where the light does not pass through.
