A battery using an active material that can function as a secondary battery has been developed by using the same material as active material of the positive electrode and the negative electrode, and a nonpolar secondary battery has been constructed. Because the terminal electrodes are not distinguished, there is no need to be aware of the mounting direction, so that the mounting process can be simplified. Also, because the positive layer and the negative layer do not need to be separately constructed, the battery manufacturing process can be simplified. Further, by connecting the nonpolar secondary batteries in series and modifying the connection of the lead-out electrodes extending from the points of connection, a battery with a different output voltage or a different battery capacity can be configured.
