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)αLn1-α)1-βMgβNiγ-δ-εAlδTε, 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 α, β, γ, δ and ε represent numerical values which satisfy 0.7
