One embodiment of the present invention provides a conductive pigment powder, which includes indium oxide, tin and gold, and having a purple color tone. Another embodiment of the present invention provides a method of producing a conductive pigment powder, which includes coprecipitating one or more hydroxides by reacting a mixed aqueous solution that includes an indium salt, a tin salt and a gold salt, with an alkaline aqueous solution, to obtain one or more hydroxides; and heating the hydroxides. Another embodiment of the present invention provides a dispersion solution, which includes the above-mentioned conductive pigment powder dispersed in one or both of an organic solvent and water, wherein the content of the powder in the solution is 0.01 to 90% by weight. Another embodiment of the present invention provides a transparent conductive film, which includes the above-mentioned conductive pigment powder. Another embodiment of the present invention provides a method of forming a transparent conductive film, which includes mixing an aqueous solution that includes indium ions, an aqueous solution that includes tin ions, and an aqueous solution that includes gold ions, to form a mixture; reacting the mixture with an alkaline aqueous solution to form at least one coprecipitated hydroxide; heating the coprecipitated hydroxide at 350 to 1100° C. to form a conductive pigment powder; mixing the conductive pigment powder with a solvent that includes one or both of an organic solvent and water, to form a dispersion solution; coating the dispersion solution on a transparent substrate to form a deposited film; and burning the deposited film at a predetermined temperature to form a transparent conductive film. Another embodiment of the present invention provides a cathode ray tube, which includes the above-mentioned transparent conductive film and a transparent substrate, wherein the transparent conductive film is formed on an outer surface of the transparent substrate.
