Abstract
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.
