Abstract: A non-aqueous electrolyte battery includes an electrode group including positive, negative and bipolar electrodes and separators interposed between these electrodes. In the positive electrode, positive electrode active material layers are formed on both side surfaces of a current collector. In the negative electrode, negative electrode active material layers are formed on both side surfaces of a current collector. In the bipolar electrode, positive and negative electrode active material layers are formed on both side surfaces of a current collector respectively. In the group, these electrodes are stacked with the interposed separators. The group includes current collecting tabs for these electrodes. Connecting portions of these tabs are arranged in different positions on an outer periphery of the group.
