Provided is a ruthenium complex that is represented by general formula (1*) and is useful as an asymmetric reduction catalyst. n (In the formula, * is an asymmetric carbon atom; R 1 is an arenesulfonyl group, and the like; R 2 and R 3 are a phenyl group, and the like; R 10 through R 14 are selected from a hydrogen atom, C 1-10 alkyl group, and the like, but R 10 through R 14 are not simultaneously hydrogen atoms; X is a halogen atom and the like; j and k are each either 0 or 1; and j+k is 0 or 2.) |
