Abstract:
A conductive sheet for a touch panel having an active area includes a first conductive layer that is formed of a first thin metal wire disposed in the active area; and a second conductive layer that is formed of a second thin metal wire disposed to overlap with the first conductive layer in the active area, in which a mesh pattern is formed of the first thin metal wire and the second thin metal wire in a case where the conductive sheet is seen from a direction perpendicular to the active area, the mesh pattern is a random pattern, an average line width of the first thin metal wire and the second thin metal wire is 0.5 μm to 3.5 μm, and an opening ratio of the mesh pattern is (92.3+X×1.6)% to 99.6%. X represents the average line width of the first and the second thin metal wire.
