Abstract
The present invention is a battery comprising: a power section containing a sulfur-based material; a distinguishing section which discolors by chemical reaction with hydrogen sulfide; and an exterior body incorporating the power section and the distinguishing section, the distinguishing section being observable from outside the exterior body. By checking discoloration of the distinguishing section or the distinguishing means, it is possible to easily detect the presence or absence of hydrogen sulfide in the battery and then judge deterioration of the battery with non-destructive inspection.
