PROBLEM TO BE SOLVED: To provide a method of manufacturing a battery which can improve a yield easily by widening the width of manufacturing conditions. SOLUTION: After a winding electrode is formed, the wiring electrode is sandwiched between sheathing members each made of a laminated film. Leads are pulled out to the outside of the sheathing member, and laminated by pressurizing while the peripheral edge of the sheathing member is being heated. In that case, the pressure is changed so that the pressure sequentially becomes high in order at multiple stages and is applied. Thus, the shock applied to the lead becomes small by this, and the disconnection of the lead is prevented. Moreover, since high pressure is applied at the final stage even if the temperature is not made higher than required, the sheathing members can be laminated certainly. COPYRIGHT: (C)2006,JPO&NCIPI
