Abstract:
A touch panel having excellent durability, in which depression is scarcely generated on the surface of the touch panel by pushing the surface with a pen, and a transparent conductive film and plate useful in the touch panel are provided. The transparent conductive film comprises a first polymer film having a transparent conductive thin layer thereon and a second polymer film having a hardcoat layer thereon, the first and second polymer films being bonded each other through an adhesive layer such that a surface having no transparent conductive thin layer of the first polymer film faces a surface having no hardcoat layer of the second polymer film, wherein work of the adhesive layer in elastic deformation is not less than 60%. The transparent conductive plate is provided with the adhesive layer, the touch panel is provided with the transparent conductive film or plate as an upper or lower electrode.
