Abstract

The present invention provides silver nano-particles that are excellent in stability and develop excellent conductivity by low-temperature calcining, a method for producing the silver nano-particles, and a silver coating composition comprising the silver nano-particles. A method for producing silver nano-particles comprising: mixing a silver compound with an aliphatic amine comprising at least a branched aliphatic hydrocarbon monoamine (D) comprising a branched aliphatic hydrocarbon group and one amino group, said branched aliphatic hydrocarbon group having 4 or more carbon atoms, to form a complex compound comprising the silver compound and the amine; and thermally decomposing the complex compound by heating to form silver nano-particles.
