PROBLEM TO BE SOLVED: To provide a new technology which can manufacture silver nanoparticles even from an insoluble silver salt. SOLUTION: This manufacturing method comprises, when manufacturing the silver nanoparticles by reducing a silver salt in a solvent, employing an insoluble salt of a silver halide (particularly silver chloride or silver bromide) for the silver salt, dissolving it in a solvent, and reducing it in the presence of a protective agent consisting of a compound soluble in a solvent and having a ligating property to silver. A preferable protective agent is a thiol like thiocholine bromide. Then, a monodisperse liquid of the silver nanoparticles is obtained, which are dispersed in the solvent while being coated and protected by the protective, agent. COPYRIGHT: (C)2003,JPO
