Provided is a roll-shaped laminate, enabling a long metal film to be wound to favorably restrain formation of a scratch on a surface of the metal film even if the laminate has a roll shape and improving productivity when the roll-shaped metal film is inputted to be used. A long first metal film and a long second metal film bonded to the first metal film through an adhesive layer are surrounded by a support. Thickness of the adhesive layer is at least 1 m, and the adhesive layer is provided to at least both end parts in the direction where the first and the second metal films are extended among the width direction of an area where the first and the second metal films are overlapped with each other when viewed from a plane. 길이가 긴 형상의 금속박을 감아서 롤 모양으로 해도 금속박 표면에 찰상이 생기는 것을 양호하게 억제하는 동시에, 롤 모양의 금속박을 투입하여 사용할 때의 생산성을 향상시키는 것이 가능한 롤 모양 적층체를 제공한다. 길이가 긴 형상의 제1 금속박과, 제1 금속박에 접착제층을 통해서 맞붙여진 길이가 긴 형상의 제2 금속박이 지지체에 둘러 감겨져 있고, 접착제층의 두께는 적어도 일부에서 1㎛ 이상이며, 또한, 평면에서 볼 때 제1 및 제2 금속박이 서로 겹치는 영역의 폭 방향 중 적어도 양단부에, 제1 및 제2 금속박이 연장하는 방향을 따라서 접착제층이 마련되어 있는 롤 모양 적층체.
