Patent ID: 8182898

Claim:
A touch panel, comprising: a first panel having a first film base with transparency and a first transparent conductive thin film provided on one surface of the first film base; and a second panel having a second film base with transparency and a second transparent conductive thin film provided on one surface of the second film base, wherein the first panel and the second panel are arranged so as to face each other with a spacer therebetween, in such a manner that the first conductive thin film and the second conductive thin film face each other, wherein the surface of the first conductive thin film has a hardness of 1 GPa or more and a modulus of elasticity of 5 GPa or more, the surface of the second conductive thin film has a center line average roughness (Ra) of 0.3 nm to 1.0 nm, and the value of the center line average roughness (Ra) of the surface of the second conductive thin film is smaller than that of the surface of the first conductive thin film, wherein the center line average roughness (Ra) was measured with scanned 1 μm square, wherein the first panel is used as an upper plate, the second panel is used as a lower plate and the upper plate is present on the pressing side of the touch panel.
