<p>PROBLEM TO BE SOLVED: To provide a transparent conductive membrane whose initial surface resistance is low at 102-103Ω/unit area level, which is excellent in heat resistant, moisture resistance, weather resistance and chemical resistance, and which maintains a low resistance for a long term, and has a good visible light permeability. SOLUTION: Aqueous solution (A) containing one kind of or more of metallic salt selected from a group of Au, Pt, Ir, Pd, Ag, Rh, Ru, Os, Re, and Cu is mixed with aqueous solution (B) containing a citric acid ion and a primary iron ion in nitrogen gas flow at, 25-95 deg.C; to deposit a coating liquid for forming a conductive membrane that contains an alloyed Ag-Pd fine particles. Then, a substrate is coated with the coating liquid to form a fine particle film thereon. Thereafter, a silica-based coating is formed thereon.</p> |
