Abstract

This invention aims to provide a transparent conductive laminate excellent in sliding durability, edge-writing durability, finger writing durability and light resistance and suitable as a movable electrode substrate for a touch panel. Further, it aims to provide a touch panel using the above transparent conductive laminate. This invention is a transparent conductive laminate that is a laminate formed by laminating a polymer film, a cured resin layer-1 and a transparent conductive layer in this order, the cured resin layer-1 having concavoconvex shapes formed by phase separation of two components and containing no fine particles that impart concavoconvex shapes, and the cured resin layer-1 having an arithmetic average roughness (Ra), measured according to JIS B0601-1994, of 0.05 μm or more but less than 0.5 μm and a ten-point average roughness (Rz), measured according to JIS B0601-1982, of 0.5 μm or more but less than 2.0 μm, and a touch panel using the transparent conductive laminate.
