Original Abstract Submitted

a method of manufacturing a power storage cell includes: a preparing step of preparing an electrode sheet including a current collecting foil and an active material layer; a bending step of bending the current collecting foil to form a bent piece; a cutting step of forming cuts in the bent piece to form connecting pieces separated from each other; and a winding step of winding the electrode sheet around a winding core. the current collecting foil prepared in the preparing step includes a main region provided with the active material layer and an end region not provided with the active material layer. in the bending step, the end region is bent with respect to the main region to form the bent piece in the end region. in the winding step, the electrode sheet is wound with each of the connecting pieces leaning toward the winding core.
