摘要：
A high-quality alkaline dry battery with small variation in the internal resistance having suppressed variations in the heights of positive electrode mixture pellets in a manufacturing process is provided. In an alkaline dry battery including: at least one hollow cylindrical positive electrode mixture pellet containing manganese dioxide and graphite; a gel negative electrode containing zinc; and a separator interposed between the positive electrode mixture pellet and gel negative electrode; manganese dioxide containing at least manganese dioxide particles having a particle diameter of 10 μm or less of 25 to 35% and manganese dioxide particles having a particle diameter of 60 to 100 μm of 15 to 25% in a particle size distribution based on volume is used.
