Zusammenfassung:	To provide a laminate and a manufacturing method for a molding that have excellent antifogging property and processing suitability in a molding step.SOLUTION: A laminate has an antifogging layer on at least one side of a substrate file. The antifogging later includes a surfactant and a thermoplastic resin. The antifogging layer has at least one peak top in each of regions where the molecular weight is 1,000 or more and 50,000 or less and where the molecular weight is 100,000 or more and 300,000 or less at the time of molecular weight distribution measurement by the GPC method.SELECTED DRAWING: None 【課題】本発明は、防曇性及び成型工程の加工適性に優れる、積層体、及び成型品の製造方法を提供することをその課題とする。【解決手段】基材フィルムの少なくとも片面に、防曇層を有する積層体であって、前記防曇層は界面活性剤と熱可塑性樹脂を含み、前記防曇層は、ＧＰＣ法による分子量分布測定の際に、分子量が１，０００以上５０，０００以下の領域と１００，０００以上３００，０００以下の領域に少なくとも１つずつピークトップを有する積層体。【選択図】なし
