摘要：
A zinc alkaline cell is formed by using an anode active material which contains a non-amalgamated zinc alloy powder having a bulk specific gravity ranging from approximately 2.90 to 3.50 (grams per cm.sup.3) and containing a predetermined amount of indium coated on a surface of the non-amalgamated zinc alloy powder containing a predetermined amount of aluminum and/or a predetermined amount of calcium as a zinc alloy powder component, other than unavoidable impurities. The zinc alkaline cell can achieve corrosive resistance and discharge performance as a cell and it is comparable with cells formed by using amalgamated zinc alloy powder which has been practically employed.
