EXAMPLE - Chain-like aggregation noble metal coated silver microparticle dispersion was prepared using hydrazine aqueous solution, colloidal dispersion liquid of noble metals coated silver microparticle, hydrogen peroxide aqueous solution and aggregating noble metals coated silver microparticle to chain-like form. Ethanol (EA), propylene glycol monomethyl ether (PGM), diacetone alcohol (DAA) and formamide (FA) were added to chain-like aggregation noble metal coated silver microparticle dispersion and coating liquid for transparent electrically conductive film formation containing 0.036% of silver, 0.144% of gold, 3.9% of water, 65.8% of EA, 20% of DAA. 0.05% of FA, was obtained. The noble metal coated silver particle with primary particle 6 nm and principal chain length of 100-500 nm was observed. Number of objects ratio of linear aggregate was 52%. Number of object ratio of pseudo linear aggregate was 34%, and the total of number of object of linear aggregate and pseudo aggregate was 86%. An electrically conductive film formed using the obtained coating liquid had surface resistance of 930 ohm/square unit, visible light permeability of 90.5%, haze of 0.2% and bottom wavelength/bottom reflectance of 530 nm/1.3%.
