PURPOSE:To obtain the title hydrogen storage alloy material which is not damaged due to pulverization of the alloy even when the occlusion and release of hydrogen are repeated by coating the aggregate of the fine particles of the hydrogen storage alloy with a metal having higher malleability and ductility than the alloy, and compacting the aggregates into a compact. CONSTITUTION:The fine particles 2 of the alloy such as La-Ni are damped in water form a slurry (expressed by A hereunder). Meanwhile, the surface of the fine particle 6 of a metal such as Al having higher malleability and ductility than the alloy is subjected to oleophilic treatment by zinc stearate, etc., the fine particles 6 are dispersed in the org. solvent such a freon-based solvent incompatible with water and not damaging the oleophilic treatment to prepare a suspension (expressed by B hereunder). The A is finely dispersed in the B while agitating to form a W/O type emulsion, the emulsion is dried to obtain a body 7 covered with the aggregate 3 of the particles 2 of the storage alloy coated with the fine metal particles 6, and the bodies 7 are compacted to form the hydrogen storage alloy material 1.
