PROBLEM TO BE SOLVED: To intend thinning, lightening and improving in reliability. SOLUTION: This thin battery has a sheet power generating element 2, positive and negative leads 3, 4 derived from the power generating element 2, and a jacketed film 5 to coat both main surfaces of the power generating element 2 and seal the surfaces of end rim parts facing each other by thermal fusion after deriving the positive and negative leads 3, 4. The end rim part of the jacketed film 5 is thermally welded with acid-denaturing polyorefin resin having a Vicat softening point of 90 deg.C or more or having a fusing point of 100 in metal-fitting. |
