PROBLEM TO BE SOLVED: To provide a roll mold manufacturing method and a roll mold manufactured in the method.SOLUTION: A roll original plate 10 is prepared to form an irregular pattern to be transferred to an inner wall surface forming a columnar hollow part; a metal layer 20 is formed on the inner wall surface 10a; a peeling assist layer 30 having a thermal expansion coefficient larger than that of the metal layer 20 is formed on at least one end part in a direction of a cylindrical axis A on the surface of the metal layer 20; the metal layer 20 and the peeling assist layer 30 are more contracted than the roll original plate 10 under an environment of a temperature of the roll original plate 10 lower than a temperature in forming the metal layer 20 and the peeling assist layer 30; the metal layer 20 is peeled from the roll original plate 10; a laminate 40 having the metal layer 20 and the peeling assist layer 30 is pulled out from the roll original plate 10; and a roll mold including the laminate 40 including the metal layer 20 on the outermost surface and having an irregular pattern 25 complementary to an irregular pattern 15 on the outer surface is produced.SELECTED DRAWING: Figure 1 |
