Abstract

In a conductive laminate, a transparent conductive thin film laminateincluding at least two transparent conductive thin films and a metal layerare formed in this order on at least one surface of a transparent base. In the transparent conductive thin film laminate, a first transparent conductive thin filmthat is closest to the metal layeris a metal oxide layer, or a composite metal oxide layer containing a principal metal and at least one impurity metal. Transparent conductive thin filmother 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
