This invention relates to a transparent conductive laminate and to a touch panel which uses the transparent conductive laminate and has excellent durability and excellent visibility. The transparent conductive laminate contains a transparent polymer substrate and a transparent conductive layer disposed on at least one of surfaces of the transparent polymer substrate, the transparent conductive layer has a surface containing micro bumps, wherein: (1) the transparent conductive laminate contains a cross-linked polymer layer (A) containing fine particles and a cross-linked polymer layer (B) between the transparent polymer substrate and the transparent conductive layer, said cross-linked polymer layer (A) is disposed between the transparent polymer substrate and said cross-linked polymer layer (B); (2) the cross-linked polymer layer (B) contacts the transparent conductive layer; and (3) the surface of said transparent conductive layer contains the bumps having an average height of 0.3 to 1 &mgr;m and a density in the range of 350 to 1,800 bumps/mm . The transparent conductive laminate can be used as an electrode substrate to provide a touch panel which has excellent writing durability, does not generate interference fringes in the touch panel, and gives non-dim and easily readable letters on the display.
