Abstract
Alloy powder for electrodes that includes particles of a hydrogen-absorbing alloy having an AB2 type crystal structure. The hydrogen-absorbing alloy includes first elements that are located in an A site in the crystal structure and include Zr, and second elements that are located in a B site and include Ni and. Mn. The hydrogen-absorbing alloy includes a plurality of alloy phases having different Zr concentrations. In each of the alloy phases, the percentage of Zr in the first elements exceeds 70 atom %.
