PROBLEM TO BE SOLVED : To provide an alkaline storage battery capable of compaction and suppression of memory effect while maintaining high output and output stability by optimizing the stoichiometric ratio of the composition of a rare earth-Mg-Ni based hydrogen storing alloy.
SOLUTION : An alkaline storage battery 10 is provided, in an outer can 17, with an electrode group consisting of a negative electrode 11 containing a hydrogen storing alloy as a main component, a positive electrode 12 containing a nickel hydroxide as a main component, and a separator 13 together with an electrolytic solution. The hydrogen storing alloy is represented by a general formula LaxNdyRe1-x-y-zMgzNin-m-vAlmTv (Re : at least one kind of element selected from rare earth elements containing Y (excepting La and Nd), T : at least one kind of element selected from Co, Mn, Zn), where following conditions are satisfied; 0.13≤x≤0.34, 0.14≤y≤0.60, 0.10≤z≤0.15, 3.50≤n≤3.75, 0.13≤m≤0.22, v≥0.
