PROBLEM TO BE SOLVED: To provide a method for manufacturing a high-purity metal nanoparticle dispersion using a low-molecular-weight dispersant, excellent in terms of dispersion stability, usable for forming printed matter or electroconductive pattern, and, when used as an electroconductive paste, capable of being sintered at a low temperature and yielding favorable physical properties; an electroconductive ink having an excellent patterning property; and an electroconductive coated object.SOLUTION: A non-aqueous metal nanoparticle dispersion having an average particle diameter of 0.1 to 200 nm is manufactured by mixing, within a microchannel, a first solution composed of a non-aqueous solution into which a fatty acid metal salt compound and a dispersant having a molecular weight of below 1000 are dispersed and/or dissolved and a second solution composed of an aqueous solution into which carbodihydrazide or polybasic acid polyhydrazide is dissolved as a reductant so as to reduce the metal salt compound. |
