Abstract
A method of producing a film includes: a disposing step of disposing a photocurable composition on a substrate; a mold contact step of bringing the photocurable composition and a mold into contact with each other; a photoirradiation step of irradiating the photocurable composition with light to form a cured product; and a mold release step of releasing the cured product and the mold from each other, in which the method further includes an alignment step of aligning the mold and the substrate with each other before the photoirradiation step, in which the photocurable composition contains at least a polymerizable compound serving as a component (A) and a photopolymerization initiator serving as a component (B), and in which the polymerizable compound has a polymerization conversion ratio of 50% or more when exposed to light under conditions of an illuminance of 0.12 mW/cmand an exposure time of 11.0 seconds.
