Abstract
The object of the present invention is to provide a reliable alkaline storage battery having a structure by which a short circuit between the electrodes can be prevented in the manufacturing procedures. To achieve this object, the present invention provides a cylindrical battery that includes an electrode assembly including a positive electrode plate and a negative electrode plate spirally wound together and sandwiching a separator. The collector plate includes a main body. One or more convex parts, each having a top extending linearly, are formed on a main surface of the main body by bending processing. A part of at least one of the convex part is cut out to form a cutout region. The collector plate is welded to the end part of the electrode assembly at the top of each convex part.
