The present invention provides a composite reverse osmosis membrane and a reverse osmosis membrane module using the same, having a high salt rejection, high water permeability, and a high rejection of organic substances such as isopropyl alcohol, which can be used to remove organic substances as well as ionic substances with suitable efficiency and economy. The highly permeable composite reverse osmosis membrane of the invention can be produced by adding alcohols or ethers or the like having a solubility parameter of 8-14 (cal/cm.sup.3).sup.1/2 to the solution containing at least one compound selected from the group consisting of a compound having two or more reactive amino groups and a polyfunctional acid halide having two or more reactive acid halide groups which is used when conducting the polycondensation of a compound having two or more reactive amino groups and a polyfunctional acid halide having two or more reactive acid halide groups on a microporous support.
