Abstract
An object of the invention is to provide a conductive film having excellent visibility. Another object of the invention is to provide a touch panel sensor and a touch panel. A conductive film according to the embodiment of the invention includes a substrate and a conductive portion which is disposed on the substrate and composed of thin metal wires having a line width of 0.5 μm or greater and less than 2 μm, the thin metal wires form a mesh pattern, a line width L μm of the thin metal wires and an opening ratio A % of the mesh pattern satisfy a relationship represented by Formula (I), and a reflectivity of the thin metal wires at a wavelength of 550 nm is 80% or less. Formula (I): 70≤A<(10−L/15).
