PROBLEM TO BE SOLVED: To provide an electroconductive film-forming liquid which imparts various functions, such as photocatalytic, antibacterial, stainproof, antistatic, and electromagnetic shielding properties, to the surfaces of various substrates, such as glass, ceramics, metals, and plastics; a structure having its surface covered with an electrically conductive film formed from the liquid; and a method for producing the liquid. SOLUTION: A tetravalent titanium salt solution (e.g. a titanium tetrachloride solution) is reacted with a basic solution in the presence of an electroconductivity-improving substance (e.g. copper chloride, silver nitrate, or silica). The resultant hydroxide is peroxidized with an oxidizing agent (e.g. hydrogen peroxide) to form an amorphous-type titanium peroxide dispersion, which can be converted into an anatase type by further heating. Thus, a titanium oxide-containing conductive film-forming liquid comprising the dispersions of both types can be produced.
