The cutting guide band includes, a first guide band having first cut lines that are inclined at a predetermined angle with respect to the transverse direction; a second guide band having second cut lines that are inclined at a predetermined angle in a direction opposite a direction of the first cut lines with respect to the transverse direction; and a third guide band having third cut lines that are inclined at a predetermined angle in the same direction as the direction of the first cut lines with respect to the transverse direction. The cutting guide band has a fourth cut line between the first guide band and the second guide band and/or between the second guide band and the third guide band, the fourth cut line being perforated and extending along the transverse direction.
