Alkaline storage battery and method for manufacturing the alkaline storage battery

An alkaline storage battery includes a spiral electrode group in which a positive electrode plate, a negative electrode plate, and a separator arranged between the positive electrode plate and the negative electrode plate are laminated, the negative electrode plate is located on the inner peripheral side of the positive electrode plate at an innermost peripheral portion, and an electrically conductive outer packaging can in which the spiral electrode group is accommodated together with an alkaline electrolytic solution. The negative electrode plate includes a negative electrode core body, a first negative electrode mixture layer carried on a surface on the outer peripheral side of the negative electrode core body, and a second negative electrode mixture layer carried on a surface on the inner peripheral side of the negative electrode core body. The negative electrode core body has a burr protruding toward the outer peripheral side at an edge portion of an innermost peripheral portion of the negative electrode core body. The thickness of the edge portion of an innermost peripheral portion of the first negative electrode mixture layer is smaller than the thickness of a portion other than the edge portion of the first negative electrode mixture layer. The height of the burr is 30% or less of the thickness of the separator.
