Functional film having functional layer and article provided with functional layer

Abstract

The present invention provides a functional film for transfer, by means of the application method, having a functional layer capable of exhibiting various functions, for example, a transparent conductive layer being low in electric resistance value, an article provided with the functional layer, and a method for producing the article provided with the functional layer. A functional film at least having a functional layer ( 4 ) on a support ( 1 ), said functional layer being releasable from the support ( 1 ), wherein the functional layer ( 4 ) is a compressed layer of functional fine particles. The compressed layer of the functional fine particles is obtained by applying a liquid in which the functional fine particles are dispersed onto the support ( 1 ) followed by drying to form a layer containing the functional fine particles, and compressing the layer containing the functional fine particles. The present invention has an advantage in the case in which a functional layer with uniform thickness is provided to an article being poor in flexibility such as plate materials.
