<P>PROBLEM TO BE SOLVED: To solve such a problem of a secondary cell that the electrolytic solution at an excess part infiltrates a laminate electrode by the force of capillary phenomenon, but in a state where a cell body is pressed by a high pressure, the electrolytic solution may not sufficiently infiltrate a cavity of the laminate electrode where the electrolytic solution is insufficient. <P>SOLUTION: The secondary cell having an excess part of electrolytic solution between the cell bodies, each housing a laminate electrode by welding the periphery of an exterior member and covering the welded portion on the periphery and the laminate electrode, is provided with pressurizing means for pressing the excess electrolytic solution from the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
