Abstract:
A transparent conductive multilayer body of the invention comprises a transparent film substrate with a thickness of 2 to 120 μm; a first transparent dielectric thin film, a second transparent dielectric thin film and a transparent conductive thin film laminated in this order on one side of the transparent film substrate; and a transparent substrate bonded to the other side of the film substrate through a transparent pressure-sensitive adhesive layer, wherein the second dielectric thin film is made of an inorganic material or a mixture of an organic material and an inorganic material, and the conductive thin film contains a crystalline material in which the content of crystal particles whose maximum particle sizes are at most 300 nm is higher than 50% by area. Such a transparent conductive multilayer body fully satisfies the pen input bending durability for a touch panel.
