Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a zinc alkaline battery with no environmental pollution, safety, and high performance using zinc alloy powder with no amalgamation, and containing no lead by using a gelled negative electrode containing zinc alloy powder and a corrosion preventive agent. SOLUTION: Zinc alloy powder containing the total of 0.001-0.05wt.% at least one element selected from the group comprising 0.01-0.1wt.% indium, 0.001-0.05wt.% gallium, 0.001-0.01wt.% bismuth, 0.001-0.005wt.% magnesium, and alkali metal (Li, Na, K), with no amalgamation and containing no lead is used as a negative active material. A gelled negative electrode 4 in which 0.005-0.5wt.% indium compound calculated in terms of indium is added to zinc alloy powder is used.
