    Abstract: An alkaline dry cell includes a positive electrode; a negative electrode; a separator disposed between the positive electrode and the negative electrode; and an electrolytic solution contained in the positive electrode, the negative electrode, and the separator, wherein the electrolytic solution contains an alkaline aqueous solution. The negative electrode contains an additive and a negative electrode active material containing zinc; and the additive contains at least one selected from the group consisting of benzoic acid, phthalic acid, isophthalic acid, and salts of the foregoing. The amount of the negative electrode active material contained in the negative electrode is from 176 to 221 parts by mass relative to 100 parts by mass of water contained in the electrolytic solution. The amount of the additive contained in the negative electrode is from 0.1 to 1.0 part by mass relative to 100 parts by mass of the negative electrode active material.
