Abstract: A conductive member is arranged on a display panel in which a plurality of pixels are arrayed in a mosaic array or a delta array, and includes a transparent insulating substrate and at least one conductive layer which has a plurality of thin metal wires and is arranged on the transparent insulating substrate, in a case of being viewed from a direction perpendicular to the transparent insulating substrate, a mesh pattern is formed by the plurality of thin metal wires, the mesh pattern is constituted by a plurality of quadrangular mesh cells having two acute angles of less than 90 degrees and two obtuse angles of more than 90 degrees, and a degree of the acute angles is 44 degrees or more and 54 degrees or less.

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.
