摘要： The present invention provides a dispersion liquid containing silver nano-particles that develops excellent conductivity by low-temperature calcining and has silver nano-particles stably and well dispersed in a dispersion solvent, and a method for producing the dispersion liquid containing silver nano-particles. [solution] A method for producing a dispersion liquid containing silver nano-particles, comprising: mixing a silver compound with amines comprising an aliphatic monoamine (A) comprising an aliphatic hydrocarbon group and one amino group, said hydrocarbon group having 6 or more carbon atoms in total; and further comprising at least one of: an aliphatic monoamine (B) comprising an aliphatic hydrocarbon group and one amino group, said hydrocarbon group having 5 or less carbon atoms in total; and an aliphatic diamine (C) comprising an aliphatic hydrocarbon group and two amino groups, said hydrocarbon group having 8 or less carbon atoms in total; to form a complex compound comprising the silver compound and the amines; thermally decomposing the complex compound by heating to form silver nano-particles; and dispersing the silver nano-particles in a dispersion solvent containing an alcohol-based solvent and an aliphatic hydrocarbon-based solvent in a specific ratio.
