Abstract
An optical film includes: a fine recess-protrusion layer having a recess-protrusion pattern, formed on a substrate film; and a fine structure body formed on the fine recess-protrusion layer. The optical film is pressed by a light guide transparent to light against one surface of an adherend applied with a photocurable resin, and light is transmitted through the light guide to cure the photocurable resin with the optical film being pressed by the light guide, thereby forming the fine structure body on the adherend.
