A separating agent for optical isomers which has a high suitability for use as a reagent for optical resolution inherent in polysaccharide derivatives and also a solvent resistance and is capable of being produced through short process steps; and a method of separating optical isomers. The separating agent comprises a polysaccharide derivative coated with a polymer and supported on a carrier, or pulverized or sphered.
