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 24, a negative electrode plate 26, and a separator 28 arranged between the positive electrode plate and the negative electrode plate are laminated, and the negative electrode plate is located on the inner peripheral side of the positive electrode plate at an innermost peripheral portion 58, and an electrically conductive outer packaging can 10 in which the spiral electrode group is accommodated together with an alkaline electrolytic solution, the negative electrode plate includes a negative electrode core body 26d, a first negative electrode mixture layer 26e carried on a surface 26g on the outer peripheral side of the negative electrode core body, and a second negative electrode mixture layer 26f carried on a surface 26h on the inner peripheral side of the negative electrode core body, the negative electrode core body has a burr 26i protruding toward the outer peripheral side at an edge portion 26k of an innermost peripheral portion 26j of the negative electrode core body, the thickness D1 of the edge portion 261 of an innermost peripheral portion 26q of the first negative electrode mixture layer is smaller than the thickness D2 of a portion other than the edge portion of the first negative electrode mixture layer, and the height H of the burr is 30% or less of the thickness of the separator.
