To provide a dimming body comprising a dimming film laminated and fixed on a transparent substrate, the dimming film having a peripheral edge sealing part that solves problems of fracture, deformation or peeling due to modification in a sealing part accompanying changes with time or changes in a use environment.SOLUTION: The dimming body has a dimming film laminated and fixed on a glass substrate, where the dimming film has a dimming layer held between first and second laminates each having a transparent electrode layer on a resin film and modulates a transmission state of light by electrically controlling the dimming layer. In the dimming body, the dimming film has a sealing part in a peripheral edge of the dimming film, the sealing part covering a side end face where the laminate structure is exposed; and The sealing part comprises a sealing material applied to cover the side end face, and has a portion (a) from a side face end where the laminate structure of the dimming film is exposed to above the resin film and a portion (b) extending from the end to a peripheral direction outside the resin film, in which the (a) portion and the (b) portion are 1 mm or more and 10 mm or less and the (b) portion is 1 or more and 5 or less times as the (a) portion.SELECTED DRAWING: Figure 1 【課題】経時的あるいは使用環境の変化に伴う封止部の変性による破断，変形，剥離の問題を解消した周縁シール部を具備する調光フィルムを透明基板に積層固定してなる調光体の提案。【解決手段】樹脂フィルム上に透明電極層を有する第１及び第２の積層体により調光層を挟持し、調光層の電気的制御により光の透過状態を変調する調光フィルムをガラス基板上に積層固定してなる調光体において、調光フィルムの周縁部では、積層構造が露出した側端面を覆うシール部を有し、シール部は、側端面を覆うように封止材が塗布形成されており、調光フィルムの積層構造が露出した側面端部から樹脂フィルム上にかかる部分（ａ）と、端部から樹脂フィルム外側の周辺方向に延出する部分（ｂ）とを有しており、（ａ）部および（ｂ）部が１ｍｍ以上１０ｍｍ以下であり、（ｂ）部が（ａ）部の１倍以上５倍以下であることを特徴とする。【選択図】図１
