Abstract: An alkaline battery has a positive electrode mixture containing manganese dioxide and a conductive material filling a tubular positive electrode can that is closed at one end. A negative electrode mixture containing a zinc powder filling on an inner peripheral side of a separator is disposed on an inside of the positive electrode mixture. The negative electrode mixture contains zinc particles with a granularity of 75 μm or less at 25 to 40 mass %. The positive electrode mixture has a plurality of tubular pellets stacked inside the positive electrode can coaxially with the positive electrode can. A sum s of lengths of gaps between the pellets is set at 1 to 14% with respect to a sum d of lengths of the pellets. Thus, a sufficient amount of the electrolyte is held in the gaps and between the pellets in the positive electrode.
