PROBLEM TO BE SOLVED: To suppress cut edge copying in a film roll.SOLUTION: A belt-like bonding tape 31 is affixed to an outer peripheral surface of a winding core 23. The bonding tape 31 is constituted of a belt-like supporting body 31a, a winding core side adhesive layer 31b formed in one surface of the supporting body 31a, and a film side adhesive layer 31c formed in the other surface of the supporting body 31a. With a part of the film side adhesive layer 31c exposed from a film leading end part 15a, a film leading end part 15b is bonded to a remaining part of the film side adhesive layer 31c, and the film leading end part 15b is fixed to the winding core 23. The supporting body 31a and the respective adhesive layers 31b, 31b function as cushioning materials. The next film 15 overlapping the end edge at the film leading end part 15a is moderately curved, and the generation of cut edge copying is suppressed. |
