Abstract
An object is to provide a method of cutting a laminate film by a circular cutter having a blade around its peripheral edge portion, including rotating the circular cutter at a blade peripheral speed of Vr by a rotational device in a forward rotational direction relative to the cutting direction, while, at the same time, moving the circular cutter at a moving speed of Vc, thereby cutting the laminate film, wherein the relative cutting speed V calculated by subtracting the blade peripheral speed Vr from the moving speed Vc falls within a range of not less than −50 m/min to not more than 30 m/min.
