There is provided a novel optically active dinickel complex and/or a production method of an optically active amine by an asymmetric Mannich reaction using the dinickel complex as a catalyst. An optically active dinickel complex of Formula (I) or Formula (I′): [where R0, R1, R2, R3, R4, R5, R6, and R7 are each independently a hydrogen atom, a halogen atom, a C1-10 alkyl group or a C1-10 alkoxy group, etc., R2 and R3 together form, together with a benzene ring bonded to them, a naphthalene ring, etc. A novel production method of an optically active amine by an asymmetric Mannich reaction using the dinickel complex as a catalyst.
