Abstract

The present invention provides a conductive laminate for a touch panel which includes a substrate, and a patterned metal layer which is visually recognized to have greater blackness when viewed from the substrate side; a touch panel; and a transparent conductive laminate. The conductive laminate includes a substrate which has two main surfaces; a patterned plated layer which is disposed on at least one main surface of the substrate and has a functional group that interacts with metal ions; and a patterned metal layer which is disposed on the patterned plated layer, in which the patterned plated layer includes a metal component constituting the patterned metal layer and the ratio of the average peak intensity resulting from the metal component contained in the patterned plated layer to the average peak intensity resulting from the metal component constituting the patterned metal layer is in a range of 0.5 to 0.95.
