Abstract: A hydrogen-absorbing alloy is represented by the general formula Ln1-xMgxNiy-a-bAlaMb (where Ln is at least one element selected from the rare-earth elements, Zr, Ti, and Y, M is at least one element selected from the group consisting of V, Nb, Ta, Cr, Mo, Mn, Fe, Co, Ga, Zn, Sn, In, Cu, Si, P, B, and Zr, 0.05?x?0.35, 0.05?a?0.30, 0?b?0.5, and 2.5?y<3.3). The Ln in the general formula includes Sm as its main component, and the hydrogen-absorbing alloy has an electrochemical capacity of 300 mAh/g or greater. An alkaline storage battery containing a negative electrode containing the hydrogen absorbing alloy.
