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 substrate, a first metal oxide layer, a metal layer, and a second metal oxide layer laminated. At least one of the first and the second metal oxide layers contains four components of Al2O3, ZnO, SnO2, and Ga2O3. X, Y, and Z are within a region surrounded by line segments between point a, point b, point c, point d, point e, and point f, in terms of (X, Y, Z) coordinates shown in a ternary diagram in FIG. 2, or on the line segments where X is a total molar ratio of the Al2O3 and the ZnO, Y is a molar ratio of the SnO2, and Z is a molar ratio of the Ga2O3, relative to the total amount of the four components. A molar ratio of the Al2O3 relative to the total amount of the four components is 1.5 to 3.5% by mole.
