PROBLEM TO BE SOLVED: To provide a new optically active polymer having excellent optical properties, a separating agent comprising the optically active polymer and a method for separation using the separating agent. SOLUTION: The optically active polymer is a new optically active polymethacrylate derivative having a urethane bond on a side chain expressed by general formula (1) (wherein, R1 is methyl, phenyl, benzyl, isopropyl or isobutyl; R2 is phenyl, naphthyl or benzyl; n is a number in the range of 2-5,000; and the mark * indicates an optically active carbon). The separating agent for an optically active substance comprises the optically active polymethacrylate derivative, and the method for separating optically active substances uses the separating agent.
