Claim Text:
1. A transparent conductive film, comprising: a transparent substrate; an undercoat layer formed on the transparent substrate; and a transparent conductive layer formed on the undercoat layer, wherein the undercoat layer has a refractive index in a range of from 1.5 to 2.0, which is higher than a refractive index of the transparent substrate and lower than a refractive index of the transparent conductive layer, the undercoat layer is made of a composition including a refractive material having a refractive index of 2.0 or greater in an amount of 40 wt. % or less with respect to a total amount of the composition of the undercoat layer, the undercoat layer includes a silicon atom and a carbon atom and satisfies formulas (1) and (2): where X (Si30) and X (C30) are a silicon atom content and a carbon atom content in % in the undercoat layer in a portion of 30 nm or less in thickness from the transparent conductive layer, and X (Si40) and X (C40) are a silicon atom content and a carbon atom content in % the undercoat layer in a portion of 40 nm or more in thickness from the transparent conductive layer.
