Abstract
Transparent conductive films produced by a series of steps comprising a coating step in which a solution obtained by dissolving an indium compound and a tin compound in an organic solvent is coated on a substrate; a preliminary drying step in which the coated substrate is dried at a temperature of 35.degree. to 100.degree. C.; a temperature rise step in which the coated substrate is heated at a temperature rise rate of 20.degree. C./min or more up to 400.degree. C. or higher; and a calcination step in which the coated substrate is calcined at a temperature of 400.degree. C. or higher, or by repeating said series of steps two or more times, have excellent properties such as strong adhesive strength to a substrate, excellent transmittance and remarkably low sheet resistance.
