Abstract

A transparent conductive film comprises a transparent substrate and a metal wiring portion formed thereon. A thin metal wire contained in an electrode portion in the metal wiring portion has a surface shape satisfying the condition of Ra/Sm>0.01 μm and has a metal volume content of 35% or more. Ra represents an arithmetic average roughness in micrometers and is equal to or smaller than the thickness of a metal wiring located in a position where the surface roughness is measured. Sm represents an average distance between convex portions and is 0.01 μm or more.
