PURPOSE:To provide uniform discharge reaction by winding a separator on to an electrode without formation of wrinkles. CONSTITUTION:A continuous cathode plate 5 holding a cathode mass 6 on a cathode current collector 7 is covered on its both sides with two continuous separator 8 and 8 which are slightly wider than the cathode plate 5. When the separator 8 is wound together with an anode plate 1 or the cathode plate 5, the separator 8 inside the cathode plate 8 and the separator 8 outside the cathode plate are free to each other due to no bonding, and the inside separator 8 slides gradually to the outside separator 8 and these separators are wound between the anode plate 1 and the cathode plate 5 without wrinkles, although these winding diameters are different. After winding, the part 15 to be bonded of the separator 8 inside the cathode plate 5 and the part 15 to be bonded of the separator 8 outside the cathode plate 5 are bonded by heating. |
