Original Abstract Submitted
To provide a battery in which electrode distortion is suppressed in connecting an electrode terminal and a current collector exposed portion. The battery includes an electrode, an exterior body surrounding the electrode, and a lead extending from the inside to the outside of the exterior body. The electrode includes a current collector and an active material layer. The electrode includes a first region where the active material layer is provided over the current collector, and a second region where the current collector is exposed. The second region of the electrode includes a third region where the current collector is folded. The lead is connected to the electrode in the third region.
