PROBLEM TO BE SOLVED: To provide a roll laminate in which the occurrence of scratches on the surface of metal foil can be suppressed satisfactorily even if the long metal foil is wound off to form a roll, and the productivity when feeding and using the roll metal foil can be improved.SOLUTION: A roll laminate is configured as follows: a long first metal foil and a long second metal foil laminated on the first metal foil through an adhesive layer are wound on a support and formed; the thickness of the adhesive layer is 1 μm or more at least in a portion; and the roll laminate is provided along the direction where the first and second metal foil are extended in at least both ends in the width direction of the region where the first and second metal foil are overlapped in a plan view.SELECTED DRAWING: Figure 1 【課題】長尺状の金属箔を巻き取ってロール状としても金属箔表面に擦り傷が生じることを良好に抑制するとともに、ロール状の金属箔を繰り出して使用する際の生産性を向上させることが可能なロール状積層体を提供する。【解決手段】長尺状の第１金属箔と、第１金属箔に接着剤層を介して貼り合わせられた長尺状の第２金属箔とが支持体に巻き付けられてなり、接着剤層の厚みは少なくとも一部において１μｍ以上であり、且つ、平面視したときに第１及び第２金属箔が重なり合う領域の幅方向の少なくとも両端部に、第１及び第２金属箔が伸びる方向に沿って設けられているロール状積層体。【選択図】図１
