In one embodiment, a secondary battery includes two or more electrode groups. The negative electrode tabs of one of the electrode groups and the positive electrode tabs of the other electrode group are arranged in rows. One of the positive electrode tabs of one of the electrode groups and the negative electrode tabs of the other electrode group is disposed at the other end in the second direction. The other is disposed at one end in the second direction at a position different from those of the negative electrode tabs of one of the electrode groups and the positive electrode tabs of the other electrode group that are connected in series.
