Abstract
Superimposing strip layers including a positive electrode strip and a negative electrode strip, which are put into layers together with a separator strip which is put between the electrode strips, are spirally wound around an outer circumference of a bobbin having an end cross section similar in shape to a center hole of a spiral electrode to form a substantially circular center hole in the spiral electrode while extracting the bobbin.
