Alkyldiamine, 1,3,5-trihydroxybenzene or 1,3-dihydroxybenzene is added as a copolymerization component to a polyfunctional aromatic amine component in the amount of 1-20% by weight with respect to the polyfunctional aromatic amine in producing a composite semipermeable membrane by laminating on a microporous substrate a polyamide formed by interfacial polycondensation between a polyfunctional aromatic amine and a polyfunctional acid halide. The composite semipermeable membrane has improved oxidation resistance while retaining excellent separation selectivity and high permeability of the crosslinked polyamide-based composite semipermeable membrane. The composite semipermeable membrane is used for desalination of brackish and sea water.
