Abstract: The transparent conductor involves a first laminate part including a transparent resin substrate and a transmittance-controlling layer, and a second laminate part including the transparent resin substrate, the transmittance-controlling layer, a metal layer containing silver or a silver alloy, and a metal oxide layer in the order presented. The first laminate part and the second laminate part are adjacent to each other in a direction perpendicular to the direction of lamination of the first laminate part and the second laminate part, and the difference between the transmittance of the first laminate part in the direction of lamination, T1, and the transmittance of the second laminate part in the direction of lamination, T2, (T2−T1) is 4% or more.

Abstract: The transparent conductor includes a transparent resin substrate, a first metal oxide layer, a metal layer containing a silver alloy, and a second metal oxide layer in the order presented. The first metal oxide layer contains zinc oxide, indium oxide, and titanium oxide, and the content of SnO2 in the first metal oxide layer is 40 mol % or less with respect to the total of four components of zinc oxide, indium oxide, titanium oxide, and tin oxide in terms of ZnO, In2O3, TiO2, and SnO2, respectively. The second metal oxide layer contains the four components, and the content of SnO2 in the second metal oxide layer is 12 to 40 mol % with respect to the total of the four components in terms of ZnO, In2O3, TiO2, and SnO2, respectively.

Abstract: A transparent conductor includes: a transparent resin base material; a first metal oxide layer; a metal layer including a silver alloy; and a second metal oxide layer, in this order. The first metal oxide layer contains at least one of tin oxide and niobium oxide. When the tin oxide and the niobium oxide are respectively set in terms of SnO2 and Nb2O5, a molar basis content of the total of SnO2 and Nb2O5 with respect to the total of metal oxides contained in the first metal oxide layer is greater than a molar basis content of the total of SnO2 and Nb2O5 with respect to the total of metal oxides contained in the second metal oxide layer, and the content in the first metal oxide layer is greater than or equal to 45 mol %.
