NOVELTY - A coating liquid containing an organometallic compound is applied on a substrate, and a coating film is formed. The coating film is dried and baked to obtain a transparent conductive film. Baking is conducted by heating the dried coating film, which comprises an organic metal compound as the main component, so that the organic component in the dried coating film is removed by heat decomposition and/or combustion to form a conductive oxide microparticle layer which is densely filled with conductive oxide microparticles.    USE - Manufacture of transparent conductive film on substrate to form transparent electroconductive substrates used as transparent electrodes in device e.g. light-emitting device, electric power generation device, display device, and input device (all claimed), e.g. LED elements, electroluminescent elements, field emission lamps, solar cells, LCDs, plasma displays, electronic paper elements, and touch panels.    ADVANTAGE - The method enables manufacture of transparent conductive films having excellent transparency, conductivity, and film strength.    DETAILED DESCRIPTION - A coating liquid containing an organometallic compound as a main component is applied on a heat-resistant substrate, and a coating film is formed. The coating film is dried to form a dry coating film, and the dry coating film is baked to obtain a transparent conductive film. Baking is conducted by heating the dried coating film, which comprises an organic metal compound as the main component, to a baking temperature equal to or greater than at least the crystallization point of an inorganic component in an oxygen-containing atmosphere at a temperature at least 10 degrees C lower than the dew point, so that the organic component in the dried coating film is removed by heat decomposition and/or combustion to form a conductive oxide microparticle layer which is densely filled with conductive oxide microparticles comprising a metal oxide as the main component. The organometallic compound consists of organic indium compound, organic tin compound, and/or organozinc compound. The metal oxide is indium oxide, tin oxide, and/or zinc oxide. INDEPENDENT CLAIMS are included for the following:    (1) transparent electroconductive substrate; and    (2) device with the substrate.
