    • A secondary battery, a jig suitable for fabrication of the secondary battery, and a method for producing a secondary battery constructed with a case accommodating the electrode assembly. The case includes a front portion terminated along opposite edges by a first wing portion and a second wing portion, and a back portion positioned opposite to the front portion, with insulating film bent along a length of a junction between the front portion and each of the first wing portion and the second wing portion, a pair of holes in the insulating film are held in parallel alignment with respect to the length of the junction, with the insulating film adhering to and covering the front portion and a corresponding one of the first wing portion and the second wing portion, in order to prevent leakage of electrolyte, and resulting corrosion of the electrically conducting metal components of the secondary battery.
