PROBLEM TO BE SOLVED: To provide a laminate which is excellent in water vapor barrier properties, transparency, an adhesive force and the like in a well balanced manner, and a protective film and an adhesive film which are each comprised of the laminate.SOLUTION: The laminate is formed by laminating the following layer (X) and layer (Y). A protective film and an adhesive film include the laminate. The layer (X) is a layer which contains as a main component, a hydrogenated block copolymer that has a hydrogenated vinyl aromatic polymer block A and a polymer block B mainly containing isobutylene. The layer (Y) is a layer which contains as a main component, a resin having a storage modulus at 25°C of 200-2,000 MPa. 【課題】水蒸気バリア性、透明性、粘着力等にバランス良く優れた積層体並びに該積層体からなる保護フィルム及び粘着フィルムを提供する。【解決手段】下記層（Ｘ）及び層（Ｙ）が積層されてなる積層体。この積層体を含む保護フィルム及び粘着フィルム。層（Ｘ）：水素化ビニル芳香族重合体ブロックＡと、イソブチレンを主体とする重合体のブロックＢとを有する水素化ブロック共重合体を主成分とする層層（Ｙ）：２５℃における貯蔵弾性率が２００〜２０００ＭＰａである樹脂を主成分とする層【選択図】なし
