Abstract
A functional film provided on a base material and having a fine uneven structure on its surface of the functional includes a coating. The coating is a coating film or a coating layer of the fine uneven structure. The coating is on a surface of the base material or a constituent layer and covers at least a bumpy portion or an entire surface of the base material. The fine uneven structure includes bumps and dents whose mutual positional relationship and shape have randomness with no regularity in terms of identity or periodicity and does not generate diffracted light.
