A process for producing an optically active amine compound, characterized by asymmetrically hydrogenating a prochiral carbon-nitrogen double bond in the presence of a ruthenium complex represented by general formula (1) or (2) (wherein P
represents an optically active diphosphine, X represents an anionic group, and Ar represents an optionally substituted arylene group).
