According to an embodiment, a battery includes an exterior container, a lid member, a plurality of electrode groups, a first lead, a second lead, and an electrode terminal. The lid member closes an opening of an inner cavity of the exterior container, and the plurality of electrode groups are stored in the inner cavity. A first current collecting tab protruding toward the lid member in a first electrode is joined with the first lead, and a second current collecting tab protruding toward the lid member in the second electrode different from the first electrode is joined with the second lead separate from the first lead. The first and second leads are together connected to the electrode terminal exposed on an outer surface of the lid member.

According to an embodiment, a battery includes an outer container, a lid member, an electrode group, a current collecting tab, an electrode terminal, a clip plate, and a lead. The lead is joined with the current collecting tab with the clip plate attached to the current collecting tab intervening therebetween, and electrically connects the current collecting tab and the electrode terminal. The clip plate includes a pair of plate parts clipping the current collecting tab therebetween and a folded part. The folded part is adjacent to the current collecting tab from one side in a lateral direction intersecting a height direction, and folds the pair of plate parts with respect to each other.
