An alkaline battery with excellent leakage resistance is provided. The positive electrode active material is a mixture of manganese dioxide and nickel oxyhydroxide, the negative electrode active material is 0.015 to 0.05% by weight of bismuth, 0.02 to 0.06% by weight of indium, and aluminum. A zinc alloy containing 0.001 to 0.02 wt%. The negative electrode is characterized by containing indium hydroxide in addition to the zinc alloy, gelling agent and alkaline electrolyte. Further, the electrolytic solution contains 0.005 to 0.04 parts by weight of silicon per 100 parts by weight of the alkaline electrolytic solution. [Selection figure] None |
