Abstract
Abstract The present invention relates to a packed battery unifying a plurality of battery cells housed in a case. The case comprises a tubular body housing the battery cells and a couple of lids closing both the end openings of the tubular body respectively, thus being arranged in a three-unit construction. This arrangement allows the case to be completely sealed off by ultrasonic wave welding.
