Abstract
A method of forming a reverse osmosis membraneof the present invention includes a coating membrane forming step of forming a coating membrane which is soluble in a predetermined solvent on a surface of a porous support substratethat is insoluble in the solvent, a carbon membrane forming step of forming a carbon membraneon the coating membrane by a physical vapor deposition which deposits carbon as a target material under an atmosphere where rare gas and nitrogen gas are contained, and a removing-by-dissolving step of removing the coating membrane by dissolving the same in the solvent after formation of the carbon membrane
