Abstract:
There is provided a transparent conductive film which has a transparent conductive layer having low specific resistance and has excellent scratch resistance. A transparent conductive film of the present invention includes: a transparent film substrate; at least three undercoat layers; and a transparent conductive layer in this order. The at least three undercoat layers include: a first undercoat layer formed by a wet coating method; a second undercoat layer that is a metal oxide layer having an oxygen deficient; and a third undercoat layer that is an SiO2 film from a side of the film substrate. The third undercoat layer has a density of 2.0 g/cm3 or more and 2.8 g/cm3 or less. The transparent conductive layer has specific resistance of 1.1×10−4 Ω·cm or more and 3.8×10−4 Ω·cm or less.
