Claim of US Patent No. 10,251,267

1. A transparent electrode comprising:a transparent substrate;
a metal conductive layer composed of a metal thin line pattern; and
a polymer conductive layer comprising a conductive polymer containing a polymer acid,
wherein the metal conductive layer being formed on/over the transparent substrate and the metal conductive layer being covered with the polymer conductive layer, and
wherein the polymer conductive layer has a surface specific resistance of 10,000?/? or smaller,
the polymer acid contains a fluorinated polymer acid and a non-fluorinated polymer acid, and
in the polymer conductive layer, a concentration of the fluorinated polymer acid increases along a direction from the transparent substrate towards the polymer conductive layer.
