<p><P>PROBLEM TO BE SOLVED: To provide a battery and the like in which airtightness between an outside sealing member and a battery case can be easily and reliably checked. <P>SOLUTION: A battery comprises: a battery case 110 having a through hole 170; a rubber sealing member 183 hermetically sealing the through hole 170; and an outside sealing member 181 covering the rubber sealing member 183 and hermetically fastened to the battery case 110. In-space gas GS in a sealing space KC formed between the outside sealing member 181 and the like includes detectable gas that can be distinguished from a gas component in atmosphere and detected. A rubber sealing section 183 of the rubber sealing member contains an organic compound generated by dissolving organic peroxide that is a vulcanization agent, and also serves as a gas supply body for supplying the organic compound to the sealing space KC as detectable gas. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
