摘要：The present invention aims at providing a composite semipermeable membraneexcellent in water permeability and salt-blocking rate, a smaller content of unreactedpolyfunctional amine components in the membrane, the composite semipermeablemembrane avoiding the necessity of a membrane washing treatment, and the presentinvention also aims at providing a process for producing the composite semipermeablemembrane. A composite semipermeable membrane having a skin layer, formed on asurface of a porous support, including a polyamide resin obtained by an interfacialpolymerization of a polyfunctional amine component and a polyfunctional acid halidecomponent, wherein the content of the unreacted polyfunctional amine component is200 mg/mor less without removing by washing of an unreacted polyfunctional aminecomponent after formation of the skin layer.
