Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a roll mold that can easily manufacture irregularities on a cylindrical surface with and accurate dimension, and to provide a roll mold that can from the irregularities with the accurate dimension using the method.SOLUTION: The method for manufacturing the roll mold includes: a step of forming fine irregularities on a plated outer circumferential surface by plating an inner circumferential surface of a cylindrical original board on which the fine irregularities are formed in the inner circumferential surface by using a material having a different heat expansion coefficient from one configuring the cylindrical original board; and a step of removing the master from the plating by heating or cooling and obtaining a seamless cylindrical plating layer.
