Addition of Mo to a Zr-Mn-V-Cr-Co-Ni, a Zr-Mn-Cr-Co-Ni hydrogen storage alloy, or those including Ti as substitution for Zr improves high-rate discharge characteristics of the hydrogen storage alloy at low temperatures. The hydrogen storage alloy is of the general formula ZrMnaVbMocCrdCoeNif, wherein 0.4</=a</=0.8, 0</=b<0.3, 0<c</=0.3, 0<d</=0.3, 0<e</=0.1, 1.0</=f</=1.5, 0.1</=b+c</=0.3, and 2.0</=a+b+c+d+e+f</=2.4, or Zr1-xTixMnaVbMocCrdCoeNif, wherein 0<x</=0.5, 0.4</=a</=0.8, 0</=b<0.3, 0<c</=0.3, 0<d</=0.3, 0<e</=0.1, 1.0</=f</=1.5, 0.1</=b+c</=0.3, x</=b+c+d+e, and 1.7</=a+b+c+d+e+f</=2.2 or Zr1-TixMnaMocMyCrdNif, wherein M is at least one selected from the group consisting of Fe, Cu, and Zn, and wherein 0<x</=0.5, 0.4</=a</=0.8, 0<c</=0.3, 0</=y</=0.2, 0<d</=0.3, 1.0</=f</=1.5, and 1.7</=(a+c+y+d+f)</=2.2. The alloy has a C15(MgCu2)-type Laves phase as a main alloy phase./!
