<p>A plurality of projections (29, 30) for projection welding are formed respectively on the opposite sides of a connector (27). The electrode plate (22) of the sealing member (20) of one of two adjacent cells (Ba1) is bonded and connected by projection welding to a side of the connector (27) by way of the projections (29), while the cell case (19) of the other cell (Ba2) is bonded and connected by projection welding to the other side of the connector (27) by way of the projections (30). In this way, a plurality of cells are connected in series.</p> |
