A functional film of the invention includes a microparticulate-containing layer containing functional microparticulates. The microparticulate-containing layer inhibits the occurrence of cracks even when drawn 10%. When the functional film includes a microparticulate-containing layer containing conductive microparticulates, the microparticulate-containing layer exhibits a surface resistivity after drawn 10% which is at most 10 times greater than the surface resistivity prior to drawing. The invention thus implements a functional film which is unsusceptible to reduction or loss of its function due to deformation.

An object of the present invention is to provide functional films which can exhibit a variety of functions using functional fine particles, in particular, a transparent conductive film having a low resistance value using conductive fine particles. The functional film of the present invention is a functional film comprising a support and a functional layer on at least one surface of the support, wherein the above functional layer contains functional fine particles, and a ratio (&sgr;1/&sgr;2) between a dispersion value (&sgr;2) obtainable from the alignment of the functional fine particles at the front surface of the functional layer and a dispersion value (&sgr;1) obtainable from the alignment of the functional fine particles at the opposite surface of the functional layer is from 1.2 to 1.85. Thereby, a sufficient contact of the functional fine particles is effected in the functional layer and the strength of the functional layer and the adhesiveness between the functional layer and the support become large, so that a transparent conductive film wherein conductive fine particles are used as the functional fine particles, for example, has a low electric resistance.
