PROBLEM TO BE SOLVED: To provide roll products that are compatible of improved hand-tear ability and strength of band-shaped members.SOLUTION: In a case where, in one cutting inducing part, a plurality of rows of virtual cutting lines arranged in the width direction are formed in the longitudinal direction, a first projection reference line extending in the longitudinal direction is set, and a plurality of virtual cutting lines in one cutting inducing part are projected on the first projection reference line to set a plurality of first projection sections, the plurality of virtual cutting lines belonging to the same row overlap each other with the first projection sections, the first projection sections of the plurality of virtual cutting lines belonging to one row and the first projection sections of the plurality of virtual cutting lines belonging to another row are separated from each other in the longitudinal direction without overlapping each other. In a case where a second projection reference line extending in the width direction is set, and a plurality of virtual cutting lines in one cutting inducing part are projected on the second projection reference line to set a plurality of second projection sections, the plurality of second projection sections are separated from each other in the width direction without overlapping each other.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2020,JPO&INPIT【課題】帯状部材の手切れ性の向上と強度とを両立させることができるロール製品を提供する。【解決手段】一つの切断誘発部の中で、幅方向に複数並べられた仮想切断線の列は、長手方向において複数列形成され、長手方向に延びる第１の投影基準線を設定し、一つの切断誘発部の中の複数の仮想切断線を前記第１の投影基準線に投影して複数の第１の投影部を設定した場合、同じ列に属する複数の仮想切断線は、互いの第１の投影部が重なり合い、一の列に属する複数の仮想切断線の第１の投影部と、他の列に属する複数の仮想切断線の第１の投影部とは、互いに重なることなく長手方向に離間し、幅方向に延びる第２の投影基準線を設定し、一つの切断誘発部の中の複数の仮想切断線を第２の投影基準線に投影して複数の第２の投影部を設定した場合、複数の第２の投影部は、互いに重なることなく幅方向に離間する。【選択図】図４
