ABSTRACT:
A band-like punching metal is made to be put on a positive electrode formed from band-like nickel fiber felt having a positive electrode active material carried therein. The positive electrode and a negative electrode are wound through a separator to thereby form an electricity generating element. In this occasion, the upper edge portion of the punching metal is projected from the upper end side of the electricity generating element so that an upper collector plate is welded to the upper edge portion of the punching metal.
