Abstract:
The present invention provides a substrate with conductive layers, capable of improving both glare preventing properties and etching characteristics; a method for fabricating the same; and a substrate with touch-panel transparent electrodes. A substrate with conductive layers has, on at least one side of a transparent film substrate, a thin film underlayer, a metal oxide layer, and a first metal layer formed in this order. The thin film underlayer comprises nickel and copper or nickel oxide and copper oxide, the metal oxide layer comprises nickel oxide and copper oxide, and the first metal layer comprises of at least one of gold, silver, and copper. The substrate preferably satisfies the following relational expressions: [1] the thickness of the thin film underlayer is 20 nm or less; [2] the thickness of the metal oxide layer is 80 nm or less; and [3] the thickness of the thin film underlayer is equal to or less than the thickness of the metal oxide layer.
