A transparent conductive sheet for a touch panel that has a surface resistivity of not more than 1,000 Ω, a total light transmittance of not less than 80%, and a haze of not more than 5%, and exhibits excellent levels of water resistance and adhesion between a transparent substrate and a transparent conductive layer. The transparent conductive sheet for a touch panel of the present invention includes a transparent substrate and a transparent conductive layer formed on top of the transparent substrate, wherein the transparent conductive layer contains a π-conjugated conductive polymer, a polyanion and an ester compound or specific polymerizable compound. The transparent conductive layer may also include conductivity improvers, dopants, other resin components and/or additives as required. A conductivity improver is preferably included to improve the conductivity.
