An optical-active cis-piperidine derivative of high chemical purity and high optical purity is efficiently produced through optical resolution of a cis-piperidine derivative mixture, racemic cis-piperidine derivative with an optical-active tartaric acid derivative or an optical-active amino acid derivative. For the optical-active tartaric acid derivative, preferred are optical-active di(paratoluoyl)tartaric acid and optical-active di(4-methoxybenzoyl)tartaric acid; and for the optical-active amino acid derivative, preferred is optical-active N-benzenesulfonylphenylalanine.
