Abstract:
Provided is a conductive film in which wire visibility of a metal wire is suppressed and visibility is improved. The conductive film includes a substrate and a conductive layer that is disposed on the substrate and consists of a metal wire, with a width of 2 μm or less, a height of 1 μm or less, and the metal wire has a metal layer, a first blackening layer, and a second blackening layer in this order from a side of the substrate. The first and second blackening layers contain a metal atom and at least one selected from the group consisting of an oxygen atom and a nitrogen atom. In the first blackening layer, a content of the metal atom at an intermediate position in a thickness direction is larger than a content of the metal atom at an intermediate position in the second blackening layer in a thickness direction.
