ABSTRACT:
A conductive film has transparency and a high level of electrical conductivity, which is used for an electromagnetic interference film hardly causing a moiré phenomenon, and the like. To achieve the above-mentioned aim, the following disclosure is disclosed. A conductive film in which a conductive portion of a random network structure is present on at least one surface of a base film, a line width of the conductive portion composing the network structure is 30 μm or less, an area of portions where the conductive portion is not present is 50% or more with respect to an area of the conductive film, and an average of ratios of a major axis length to a minor axis length of an area surrounded by the network of the conductive portion, in which the base film is exposed, is larger than 1 and is equal to or less than 3.5.
