Abstract
A battery includes an electrode body and an internal terminal attached to the electrode body. The electrode body includes positive electrode sheets, negative electrode sheets, and separators. The positive electrode sheets and the negative electrode sheets are alternately stacked in a stacking direction, with each separator interposed between associated adjacent ones of the positive electrode sheets and the negative electrode sheets. The positive electrode sheets and the negative electrode sheets each include a collector foil. At least either portions of the collector foils of the positive electrode sheets or the negative electrode sheets are protruded beyond the separators in one direction. The protruded portions of the collector foils are piled in a stack in the stacking direction. The internal terminal includes a connector connected to the stack of the protruded portions of the collector foils. The stack of the protruded portions is bent around a base end of the protruded portions of the collector foils.
