Summary:To provide a multilayer structure having high transmissivity, and having jointly easy cleanability (antifouling property) and excoriation resistance.SOLUTION: A multilayer structure has a transparent substrate, a smooth hydrophilic layer provided as an outermost layer on one surface side of the transparent substrate, and an antireflection layer having a plurality of uneven structures provided as an outermost layer on the opposite surface side thereof, in which a roughness (average height difference of the uneven structure) and a pitch (mean distance between peaks of mutually adjacent convex parts) of the antireflection layer are in the range of 60 nm-800 nm.SELECTED DRAWING: None 【課題】高い透過率を有し、易清掃性（防汚性）と耐擦傷性とを兼ね備えた多層構造体を提供する。【解決手段】透明基材と、その透明基材の一つの面側の最外層として設けられた平滑な親水性層と、その反対面側の最外層として設けられた複数の凹凸構造を有する反射防止層とを有しており、該反射防止層のラフネス（凹凸構造の平均高低差）およびピッチ（互いに隣接する凸部の頂点間の平均距離）が６０ｎｍ〜８００ｎｍの範囲である多層構造体。【選択図】なし
