Abstract
In a thin type sealed cell utilizing a cell case made of a laminated material, a storage life and reliability of the cell is increased by preventing a sectional surface at an end of the laminated material from being exposed in the cell case, and thereby a leakage of an electrolyte out of the cell and a short circuit in the cell are avoided. This is achieved by disposing a resin layer on the inner surface of the cell case composed of a sheet type laminated material, and covering the sectional surface existing inside the cell case with resin.
