Zusammenfassung:	In one embodiment, a battery includes an exterior unit, an electrode group, an electrode terminal, tab bundles and a lead. The electrode group is housed in an interior cavity of the exterior unit, and the electrode terminal is exposed to an outside. Current collecting tabs are stacked in the thickness direction of the electrode group in each of the tab bundles having the same polarity. The tab bundles protrude from the electrode group to the same side in the length direction of the electrode group. The lead establishes an electric connection between the respective tab bundles and the electrode terminal. The tab bundles are bonded to the lead at positions deviated from one another in the thickness direction, and are mounted on the lead from the same side in the thickness direction.
