Abstract

Provided is a photocurable composition used for forming a resin layer of a concave-convex structure including a substrate and a resin layer provided on the substrate and having fine concavities and convexities formed on a surface thereof. A cured film of the photocurable composition has a surface free energy of 15 mJ/mto 40 mJ/mas measured based on the Kitazaki-Hata theory and a hardness of 0.05 GPa to 0.5 GPa as measured using a nanoindenter.
