PROBLEM TO BE SOLVED: To obtain a coating material for forming a transparent conductive membrane capable of providing an excellent conductivity, transparency, low discoloring properties and useful as a transparent, conductive and low reflective membrane by including a colloidal metal fine powder, a dispersed stabilizer adsorbed thereon, an aggregation inducer and water. SOLUTION: This coating material for forming a transparent conductive membrane comprises (A) a colloidal metal fine powder (e.g. the one made of gold, silver, copper, aluminum, etc., and containing fine particles having <=0.1μm average particle diameter and <=0.005μm first particle diameter), (B) a dispersion stabilizer adsorbed on the component A (e. g. a water-soluble polymer compound such as a carboxylic acid, a sulfonic acid, polyvinyl alcohol, etc.), (C) an aggregation inducer (e.g. an alkali metal ion or ammonium ion) for aggregating the component A when being dried and (D) water, and if necessary (E) a water-soluble solvent such as alcohols or cellosolves having a boiling point higher than that of the water.
