Document Type and Number:
Japanese Patent JP5932098
Kind Code:
B2
Abstract:
Provided is a transparent conductive film having excellent moist-heat resistance and capable of maintaining a low specific resistance value. The present invention relates to a transparent conductive film including: a transparent film substrate; at least three undercoat layers; and a crystalline transparent conductive layer in this order, wherein: 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 a metal oxide layer having a stoichiometric composition from a side of the film substrate; the transparent conductive layer has a surface roughness Ra of 0.1 nm or more and 1.6 nm or less; and the transparent conductive film has specific resistance of 1.1×10−4 Ω·cm or more and 3.8×10−4 Ω·cm or less.
