Summary:PROBLEM TO BE SOLVED: To provide a catalyst composition for obtaining an optically-active alcohol compound in a high yield and a high selectivity. SOLUTION: The catalyst composition is composed of a ruthenium complex represented by general formula (1) (wherein, X and Y each represent a hydrogen atom, halogen atom, carboxyl group, or other anion group, R1, R2, and R3each represent a hydrocarbon group which may have a substituent, both the R1and the R2may form a carbon chain ring which may have a substituent, n is an integer of 1 to 4, R6, R7, and R8each represent a hydrocarbon group which may have a hydrogen atom or a substituent, m is an integer of 1 to 4, and both of PR1R2R3and NR6R7R8are an optically-active group).
