Function transfer product, functional layer transfer method, packed product, and function transfer film roll

Abstract

A function transfer product () is provided with a carrier () having a concavo-convex structure () of nanostructure, and a functional layer () provided on the concavo-convex structure (). The functional layer () is beforehand provided on the surface of the concavo-convex structure (), and is directly brought into contact with one main surface of a target object (), and then the carrier () is removed from the functional layer () to transfer the functional layer () to the target object (). An average pitch of the concavo-convex structure () ranges from 1 nm to 1500 nm, the functional layer () contains a resin, and a ratio (Ra/lor) between surface roughness (Ra) on the exposed surface side of the functional layer () and a distance between a top position of a convex-portion of the concavo-convex structure () and the exposed surface of the functional layer () is 1.2 or less. Further, the functional layer () is arranged inside concave portions (), and the exposed surface thereof is in a non-liquid state at a temperature of 20° C. under light shielding. It is possible to add the function onto the target object () with high accuracy.
