摘要： A method for manufacturing a light transmissive film having a cured resin layer with a fine concavo-convex structure on a surface of a base material film is provided. The method includes sandwiching an active energy ray-curable composition including a mold dissolving component between a mold having an inversion structure of the fine concavo-convex structure and the base material film, obtaining a light transmissive film in which a cured resin layer having the inversion structure of the mold transferred is formed on one surface of the base material film, and separating the obtained light transmissive film and the mold. Thus, it is possible to productively manufacture a light transmissive film, and to prevent the deposition of an attachment on the mold surface and the contamination of the mold surface. Moreover, a light transmissive film can be manufactured having excellent performances, such as antireflection properties.
