Abstract
A cell such as a nonaqueous electrolytic secondary cell includes a plurality of power-generating elements which each include a strip-like positive electrode and a strip-like negative electrode that are both wound into an elliptic cylinder with a separator being interposed therebetween, where each power-generating element has a peripheral face including at least a flat portion. The cell also includes a cell case for housing the power-generating elements, where the cell case has an opening, and a cover hermetically sealing the opening of the cell case. The flat portion of each power-generating element is superposed on the flat portion of the adjacent power-generating element, and a sheet member is wound around peripheries of the superposed power-generating elements to fasten the power-generating elements such that the power-generating elements are integrated.
