PROBLEM TO BE SOLVED: To prevent the pulverization of a hydrogen storage alloy without causing the reduction of the amount of hydrogen to be occluded, and also to reduce the alloy cost by the reduction of the content of Co. SOLUTION: This hydrogen storage alloy has a two phase crystal structure of a base phase with a CaCu5 type crystal structure and a phase with a solidified structure of a three-dimensional network structure being present so as to be entangled in the base phase, these two phases have almost equal lattice constants, and also, the above phase with a three-dimensional network structure is the one similar to a CaCu5 type simuntaneously occulding or discharging hydrogen when the base phase occuludes or discharges hydrogen. |
