The present invention pertains to a transparent conductive layered structure having a transparent substrate and a transparent 2-layer film consisting of a transparent conductive layer and a transparent coating layer formed in succession on this substrate, that is used for instance, in the front panel of displays, such as CRTs, etc. The above-mentioned transparent conductive layer has as its main components noble metal microparticles with a mean particle diameter of 1 to 100 nm composed of gold and/or platinum and silver and containing 5 to 95 wt % gold and/or platinum, colored pigment microparticles with a mean particle diameter of 5 to 200 nm, and binder matrix. The noble metal microparticles are mixed at a ratio of 1 to 40 parts by weight per 1 part by weight colored pigment microparticles. Moreover, it is characterized in that the transparent 2-layer film has a surface resistance of 10 to 5000 &OHgr;/&square;, reflectance of 0 to 2.5%, visible light transmittance of 40 to 75%, and standard deviation of transmittance at each wavelength in 5 nm intervals of the visible light wavelength region being 0 to 5%.
