Claim:
1. An electroconductive film comprising: a base material film provided with a light transmissive base material, and one or more functional layers laminated on a single or both sides of the light transmissive base material, a transparent electroconductive layer, which is provided on the functional layer, and patterned, and a lead-out electrode electrically connected with the transparent electroconductive layer, wherein wherein the high refractive index layer in the first configuration or the second configuration has a refractive index of 1.55 or more and 1.75 or less, and the low refractive index layer in the first configuration or the third configuration has a refractive index of not less than 1.35 but less than 1.55, wherein the high refractive index layer in the first configuration or the second configuration comprises a high refractive index particle and a binder resin, and the low refractive index layer in the first configuration or the third configuration comprises a low refractive index particle and a binder resin, or comprises a low refractive index resin, wherein when the base material film is irradiated with light from a surface side of the functional layer while an incidence angle is varied every five degrees in a range of 5° or more and 75° or less, when a normal direction of a surface of the base material film is 0°, to determine a* and b* values of the base material film in a L*a*b* color system from reflected light toward each regular reflection direction, a variation of the a* values is 1.0 or less, and a variation of the b* values is 3.0 or less with respect to the base material film, and wherein each of the one or more functional layers has a thickness and a refractive index that are selected to obtain the variation of the a* values that is 1.0 or less and the variation of the b* values that is 3.0 or less.
