Abstract
Provided is a method of manufacturing a structure having a transparent fine uneven structural body formed by hot water treatment, in which a finer uneven structure is formed. Provided is a method of manufacturing a structure, the method being for manufacturing a structure including a substrate, and a transparent fine uneven structural body which is formed on a surface of the substrate by hot water treatment, including: a first step of forming a precursor film of the transparent fine uneven structural body on the substrate; a second step of forming a fine uneven structure on a surface of the precursor film; and a third step of subjecting, to hot water treatment, the precursor film on which the fine uneven structure is formed to form the transparent fine uneven structural body in which a peak value ν0 of space frequency of the unevenness of the fine uneven structure formed in the second step satisfies ν <ν0 (Expression I). In Expression I, ν0 represents a peak value of space frequency of the fine uneven structure, and ν represents a peak value of space frequency of the transparent fine uneven structural body in a case in which the fine uneven structure is not formed on the surface of the precursor film.
