摘要：
A secondary battery deterioration judging device is provided with an overdischarge detecting section for detecting the overdischarge of a secondary battery, the deterioration of which is to be judged, a computing section for integrating a value indicating the deterioration of the secondary battery while the overdischarge is detected by the overdischarge detecting section, and a judging section for judging a deterioration state of the secondary battery based on an integration value obtained by the computing section.
