CONDUCTIVE LAMINATE, TRANSPARENT CONDUCTIVE LAMINATE WITH PATTERNED WIRING, AND OPTICAL DEVICE

摘要

An object of the present invention is to suppress an increase in resistivity of a transparent conductive layer when a metal layer is removed by etching from a conductive laminate having the metal layer on the transparent conductive layer. In the conductive laminate, a transparent conductive thin film laminate 2 including at least two transparent conductive thin films and a metal layer 3 are formed in this order on at least one surface of a transparent base. In the transparent conductive thin film laminate 2, a first transparent conductive thin film 21 that is closest to the metal layer 3 is a metal oxide layer, or a composite metal oxide layer containing a principal metal and at least one impurity metal. Transparent conductive thin film 22 other than the first transparent conductive thin film is a composite metal oxide layer containing a principal metal and at least one impurity metal. The content ratio of impurity metal in the first transparent conductive thin film is not the highest of content ratios of impurity metal in the transparent conductive thin films which form the transparent conductive thin film laminate 2. The abovementioned problems are solved by such a configuration.
