摘要

A method for producing a substrate having a concave convex pattern has a step (S2) for forming a coating film by coating the substrate with a sol solution comprising a silica precursor a step (S3) for drying the coating film a pressing step (S4) for pressing a mold having a concave convex pattern on the dried coating film with a pressing roll a step (S6) for peeling the mold from the coating film and a step (S7) for firing the coating film on which the concave convex pattern has been transferred. The coating film is dried so that the ratio of coated film weight to dried weight when fired at 100°C in the drying step is 1.4 to 8.8. The coating film may also be heated in the pressing step.
