Abstract

By combining crimping fixing and laser welding, a collector attached to a substrate of an electrode assembly is fixed to a terminal. A negative electrode terminalA has a terminal portion formed on one side of a flange portion, and a cylindrical crimping memberon the other side. The cylindrical crimping memberis inserted through openings formed in a first insulating member, a sealing plate, a second insulating member, and a negative electrode collector. The cylindrical crimping memberis crimped in a diameter-increasing direction, and is mechanically fixed in a countersunk holeof the negative electrode collector. A peripheral portion of a thin-walled portionhaving a thickness smaller than those of other portions formed at the tip end portion of the cylindrical crimping memberis thoroughly adhered and welded by a high energy beam to the edge of the countersunk hole
