PROBLEM TO BE SOLVED : To provide a rare earth-Mg-Ni-based hydrogen storage alloy in which the drop of a working voltage is suppressed even after long-term standing and the high working voltage is obtained when the alloy is applied to a nickel hydrogen secondary battery. SOLUTION : The nickel hydrogen secondary battery includes particles (36) of the hydrogen storage alloy in a negative electrode (26). The hydrogen storage alloy has a composition expressed by general formula (LaaNdbAcDd)1-wMgwNixAlyTz. In formula, A, D and T respectively denote elements of at least one kind selected from a group consisting of Sm and Gd, a group consisting of Pr, Eu and the like, a group consisting of V, Nb, etc.; subscripts a, b, c, d satisfy the relationships respectively expressed by a≥0, b≥0, c>0, 0.1>d≥0, a+b+c+d=1, and subscripts w, x, y, z are respectively in ranges shown by 0
