Abstract (en)

[origin: EP3685943A1] Provided is a method for producing silver nanoparticles having high monodispersity. The method for producing silver nanoparticles comprises steps of: forming a silver-amine complex as a precursor by reacting a silver compound with an amine compound in the presence of a dispersant; and precipitating a silver nanoparticle from a chemical reaction system containing the silver-amine complex, wherein the amine compound contains at least one compound represented by chemical formula (1).
