To provide a laminate including a thin film structure having a fine protrusion and recess structure on the surface thereof, which allows the thin film structure to be commercially distributed for use by a customer without contamination or damages, and which suppresses degradation even after stored.SOLUTION: The laminate includes a thin film structure and holding films, in which a first holding film is laminated on one surface of the thin film structure, a second holding film is laminated on the other surface of the thin film structure, and the thin film structure has a fine protrusion and recess structure on both surfaces thereof. The laminate is at least characterized in that 0<P1, 0<P2 and P1≠P2 are satisfied, where P1 is a peeling strength on the interface between the first holding film and the thin film structure and P2 is a peeling strength on the interface between the second holding film and the thin film structure.SELECTED DRAWING: Figure 1 【課題】表面に微細凹凸構造を有する薄膜構造体を、汚損及び破損することなく顧客が使用できるように市場に流通させることが可能な、当該薄膜構造体を備える積層体であって、保存後においても劣化が抑制された積層体の提供。【解決手段】薄膜構造体と、保持フィルムとを備える積層体であって、前記薄膜構造体の一方の面上に、第１保持フィルムが積層されるとともに、前記薄膜構造体の他方の面上に、第２保持フィルムが積層され、前記薄膜構造体は、両面に微細凹凸構造を有し、前記第１保持フィルムと前記薄膜構造体との界面における剥離力をＰ１とし、前記第２保持フィルムと前記薄膜構造体との界面における剥離力をＰ２としたときに、０＜Ｐ１、０＜Ｐ２、及び、Ｐ１≠Ｐ２を満たす、ことを少なくとも特徴とする、積層体。【選択図】図１
