A transparent conductive laminate of the invention comprises: a transparent film substrate; a transparent conductive thin film provided on one side of the transparent film substrate; and a transparent base substrate bonded to another side of the transparent film substrate with a transparent pressure-sensitive adhesive layer interposed therebetween, wherein the transparent conductive thin film comprises a first transparent conductive thin film made of an indium-tin complex oxide in which SnO<SUB>2</SUB>/(SnO<SUB>2</SUB>+In<SUB>2</SUB>O<SUB>3</SUB>) is from 2 to 6% by weight and a second transparent conductive thin film made of an indium-tin complex oxide in which SnO<SUB>2</SUB>/(SnO<SUB>2</SUB>+In<SUB>2</SUB>O<SUB>3</SUB>) is more than 6% by weight and not more than 20% by weight, the first and second transparent conductive thin films are formed in this order from the transparent film substrate side, the thickness t<SUB>1 </SUB>of the first transparent conductive thin film and the thickness t<SUB>2 </SUB>of the second transparent conductive thin film have the following relationships: ( 1 ) t<SUB>1 </SUB>is from 10 to 30 nm; ( 2 ) t<SUB>2 </SUB>is from 5 to 20 nm; and ( 3 ) the sum of t<SUB>1 </SUB>and t<SUB>2 </SUB>is from 20 to 35 nm, the first transparent conductive thin film and the second transparent conductive thin film are both crystalline films, and the transparent base substrate is a transparent laminated base substrate comprising at least two transparent base films laminated to one another with a transparent pressure-sensitive adhesive layer interposed therebetween. The transparent conductive laminate has satisfactory reliability at high temperature and high humidity for touch panels and also has pen input durability and surface pressure durability.
