PROBLEM TO BE SOLVED: To establish a method for producing an alloy particle in which two or more kinds of metals are uniformly made into solid solution at an atomic level. SOLUTION: A hydrogen absorption/discharge cycle where hydrogen is made to absorb into a metal particle comprising two or more kinds of metal atoms, and in which two or more kinds of crystal lattices are inherent, and at least a part of the hydrogen is discharged is applied for prescribed times, thus the alloy particle comprising the two or more kinds of metal atoms, and in which crystal lattices of single kind is are inherent is obtained. The production method is not only suitable for producing an alloy particulate having small particle diameters, but also can be applied even to the combination of metals (e.g., palladium and platinum) in which phase separation occurs even if being melted and mixed. By utilizing the same, a new alloy particle useful as a catalyst, a hydrogen storage body or the like can be produced. COPYRIGHT: (C)2006,JPO&NCIPI
