PURPOSE:To reduce the inner resistance and to improve the discharge property, by furnishing the winding start part of a thin metal plate between the winding end part of a separator and the winding end part of a negative electrode plate, and winding the thin metal plate one round so as to connect the winding start part and the winding end part of the thin metal plate electrically. CONSTITUTION:Between the winding end part of a separator (1)-13 and the winding end part of a negative electrode plate, the winding start part 11'' of a thin metal plate 11 is placed. The thin metal plate 11 is wound one round, and, the winding end part 11' of the thin metal plate 11 and the winding start part 11'' of the thin metal plate 11 are superposed through a negative electrode plate and a separator (2)-13', while the winding start part 11'' of the thin metal plate 11 and the winding end part 11' are directly connected electrically through the winding end part of the negative electrode 12. |
