An alkaline storage cell has a positive electrode, a negative electrode containing a hydrogen storage alloy, and an alkaline electrolyte. The hydrogen storage alloy has a composition expressed by a general expression: ((PrNd).sub..alpha.Ln.sub.1-.alpha.).sub.1-.beta.Mg.sub..beta.Ni.sub..gam- ma.-.delta.-.epsilon.Al.sub..delta.T.sub..epsilon., where Ln represents at least one element chosen from a group consisting of La, Ce, etc., T represents at least one element chosen from a group consisting of V, Nb, etc., and subscripts .alpha., .beta., .gamma., .delta. and .epsilon. represent numerical values which satisfy 0.7<.alpha., 0.05<.beta.<0.15, 3.0.ltoreq..gamma..ltoreq.4.2, 0.15.ltoreq..delta..ltoreq.0.30 and 0.ltoreq..epsilon..ltoreq.0.20.
