Abstract

A method for producing a substrate having a concavity and convexity pattern includes: a step for applying a sol containing a silica precursor on a substrate to form a coating film; a step for drying the coating film; a pressing step for pressing a mold having a concavity and convexity pattern against the dried coating film with a pressing roll; a step for peeling off the mold from the coating film; and a step for baking the coating film to which the concavity and convexity pattern has been transferred. The coating film is dried in the drying step so that the ratio of weight of the coating film to dried weight of the coating film is in a range of 1.4 to 8.8, the dried weight being obtained by baking the coating film at a temperature of 100 degrees Celsius. The coating film may be heated in the pressing step.
