Abstract: A laminated film, including an adhesive layer peelably laminated on a base film, and a carrier film overlapping each other are passed between a bladed roller including a plurality of disk-shaped slitting blades arranged at a pitch of 0.5 mm or less and an anvil roller with the laminated film on the bladed roller side to slit the laminated film by score cutting. The slitting blades have a blade angle of 30° or less. By doing so, the laminated film including the adhesive layer peelably laminated on the base film is silt to have a tape width of 0.5 mm or less in such a way that the base film and the adhesive layer do not peel apart and the protrusion of the adhesive layer is suppressed.
