PROBLEM TO BE SOLVED: To provide a roll article of a dry film capable of reducing the step due to a resin layer by reducing the step at a winding starting part on a bobbin, securing the reliability of the film thickness, enhancing the working effectiveness of a slitter, and reducing the cost of the roll article. SOLUTION: The roll film is structured so that a first film is coated with the resin layer and furthermore a second film is laminated, in which the ends of the two films are deviated from each other in the winding staring part when winding is made on the bobbin to fabricate the roll film. This permits reducing the step due to the resin layer. COPYRIGHT: (C)2005,JPO&NCIPI
