Abstract

Provided are silver nanoparticles having excellent dispersion stability and capable of forming on a substrate a silver element, such as a silver film or line, having excellent electrical conductivity and adhesivity through heating. A method for producing the silver nanoparticles, its dispersion liquid, and a substrate having a silver element formed thereon using the dispersion liquid are disclosed. The silver nanoparticles contain silver compound (A) of formula (1): amine compound (B) having a primary amino group; and polymer (C) obtained by polymerization of a monomer composition containing diol (meth)acrylate compound (c1) having a urethane bond of formula (2): (R: hydrogen atom or methyl group; R: —(CH2)n-; n: 1 to 4), and at least one monomer (c2) selected from (meth)acrylate monomers, acrylamide monomers, vinyl monomers, vinyl ether monomers, or monomers having an epoxy group.
