<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a composite semi-permeable membrane having high solute removability and high water permeability. Ž<P>SOLUTION: The manufacturing method of the composite semi-permeable membrane having a polyamide separation functional layer includes: a step A of forming the polyamide separation functional layer by the interfacial polycondensation of a polyfunctional amine with a polyfunctional acid halide on a microporous support membrane; a step B of bringing the polyamide separation functional layer into contact with ammonia; and a step C of bringing into contact with an isocyanating reagent.
