PROBLEM TO BE SOLVED: To provide the assembly method of an electricity storage system excellent in productivity. SOLUTION: In the assembly method of the electricity storage system, a plurality of capacitor cells (151) are aligned in parallel in which one pair of plate-like collector electrodes (153, 154) are derived from a film package (152), and the plurality of the capacitor cells are connected in series by connecting the collector electrodes of the each capacitor cell to the collector electrode of the adjoining separate capacitor cell. In this method, the two electrodes to be connected are held in a status of being superposed, then, the two collector electrodes are welded in a status of being superposed and held. Or, the two collector electrodes to be connected are held in the status of being superposed, and then, in the status of being superposed and held, the two collector electrodes are sheared from the direction of board thickness. Subsequently, the sheared two collector electrodes are welded in the status of being superposed and held. COPYRIGHT: (C)2007,JPO&INPIT
