To produce a hydrogen absorbing alloy powder which is an aggregate of alloy particles each including a metal matrix and added-components, an aggregate of metal matrix particles and an aggregate of added-component particles are used, and mechanical alloying is carried out. In this case, the relationship between the particle size D of the metal matrix particles and the particle size d of the added-component particles is set at d.ltoreq.D/6. Thus, the milling time can be shortened remarkably.

Pour produire une poudre absorbante d'alliage d'hydrogène qui est un agrégat des particules d'alliage chacun comprenant une matrice en métal et des ajouter-composants, un agrégat des particules de matrice en métal et un agrégat des particules d'ajouter-composant sont employés, et l'alliage mécanique est effectué. Dans ce cas-ci, le rapport entre la dimension particulaire D des particules de matrice en métal et la dimension particulaire d des particules d'ajouter-composant est placé à d.ltoreq.D/6. Ainsi, le temps de fraisage peut se raccourcir remarquablement.
