A hydrogen storage alloy preferably used for electrodes in alkaline rechargeable battery is of the general formula: Zr1.2-aTiaMnvAlwNixMyCrz wherein M represents at least one element selected from the group consisting of Si, Zn, Sn, Fe, Mo, Cu and Co; and wherein 0.1</=a<1.2, 0.4</=v</=1.2, 0<w</=0.3, 0.8</=x</=1.6, 0</=y</=0.2, 0</=z</=0.3, and 1.7</=(v+w+x+y+z)</=2.7. The alloy has at least one of a C14-type Laves phase of a crystal structure similar to that of MgZn2 and a C15-type Laves phase of a crystal structure similar to that of MgCu2 as a main alloy phase.
