PROBLEM TO BE SOLVED: To industrially advantageously produce both optical isomers of (R) and (S) configurations of a 2-substituted amino-4-arylbutyronitrile in good yield. SOLUTION: The method for producing an optically active 2-substituted amino-4-arylbutyronitrile or its salt comprises separating the stereoisomers present in a 2-substituted amino-4-arylbutyronitrile or its salt.
