Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a light control sheet in which a removal between a substrate and a light control layer is prevented.SOLUTION: A light control sheet includes a surface layer on one side of a substrate. The surface layer includes a light control layer. The light control layer includes a light transmission part having a plurality of groove parts on one side and a light control part having a lower refractive index than the light transmission part in a groove part. The surface layer has a water vapor permeation rate of 40 g/(m/24h) or less.SELECTED DRAWING: Figure 1 【課題】本発明は、基材および光制御層間の剥離が抑制された光制御シートを提供することを主目的とする。【解決手段】本発明は、基材の一方の面に表面層を有し、上記表面層は、光制御層を含み、上記光制御層は、一方の表面に複数本の溝部を有する光透過部および上記溝部内に、上記光透過部より屈折率が低い光制御部を有し、上記表面層の水蒸気透過率が４０ｇ／(ｍ２・２４ｈ)以下であることを特徴とする光制御シートを提供することにより、上記課題を解決する。【選択図】図１
