PROBLEM TO BE SOLVED: To maintain the characteristics of a resin film by eliminating swell marks appeared therein.SOLUTION: In the method for producing a resin film roll 1 where a resin film 2 and intermediate paper 3 are abutted so as to be slid and are integrally carried, and the resin film 2 and the intermediate paper 3 are wound into a roll shape to produce the resin film roll 1 in which the resin film 2 and the intermediate paper 3 are mutually laminated, the surface roughness of the intermediate paper 3 is higher than the surface roughness of the resin film 2. |
