Abstract
The present invention provides a method for producing silver particles, including the steps of: mixing a thermally decomposable silver compound and an amine compound to prepare a silver-amine complex as a precursor; and heating the silver-amine complex at a heating temperature equal to or higher than the decomposition temperature of the silver-amine complex to precipitate silver particles, the silver compound being silver carbonate, the amine compound being terminated with a primary amino group on at least one end and containing a predetermined hydrocarbon group R with a carbon number of 4 to 10. In the method of the present invention, silver particles with the particle size controlled to fall within the range of 20 nm to 200 nm in terms of an average particle size can be produced.HN—R  [Chemical Formula 1]
