Abstract
A transparent conductive film includes a polymer layer disposed on one of surfaces of a film base formed from polyester and biaxially stretched, and a transparent conductive layer disposed on the polymer layer. A difference between a refractive index η1 of the film base and a refractive index η2 of the polymer layer, |η1−η2| is set to at most 0.02. The polymer layer contains particles of metal oxide having a refractive index ηP of at least 1.80, and a binder holding the particles and having a refractive index ηB of at least 1.60. A mass ratio of the particles of metal oxide with respect to the binder is set to be more than 0% and equal to or less than 100%.
