    摘要: The present invention provides a film roll comprising an electrified portion at at least part in the transverse direction of a film that is wound into a roll, in which the difference between the maximum width and the minimum width of the electrified portion is 10 mm or less. In this manner, side slipping can be reliably prevented while securing escapeways for air at the edges, and a film roll having no side slips, wrinkles, deformation, decentering, or the like can be manufactured. The film roll of the present invention can be manufactured by intermittently electrifying the film at a predetermined cycle, the ratio of the time duration of the electrification in the cycle being 10 to 80%. The film roll of the present invention has a high adhesive force and does not suffer from slipping during evacuation in a vacuum evaporator. Thus, the film roll is suitable as a master roll for metallization and can be suitably applied to various uses such as magnetic tapes, packaging materials, capacitors, and the like.
