PROBLEM TO BE SOLVED: To provide a battery having a structure allowing production with good productivity and a shape which can be shared with battery systems whose voltage specification is different while certainly preventing the occurrence of various troubles. SOLUTION: A sealing matter 22 arranged at one end opening of a battery case 20 operates as one terminal part 21. The whole of annular peripheral surface having a determined width at outer peripheral surface of the case 20 operates as other terminal part 23. Another end surface of the case 20 is electrically insulated by pasting electric insulative films 28, 29. Heat-shrinkable labels 24, 27 on which thermal adhesives is applied are wound on whole surface except for the terminal part 23, and the case 20 is electrically insulated by bonding by adhesives in which adhesion is created by heat. As a result, the terminal part 23 becomes recessed ring shape between labels 24, 27. |
