A production method of composite silver nanoparticle including the steps of: arranging at least an alcohol solvent selected from alcohols with a carbon number of 1 to 12 composed of methanol, ethanol, propanol, buthanol, pentanol, hexanol, heptanol, octhanol, nonanol, decanol, undecanol and dodecanol; preparing an alcohol solution by mixing a silver salt into the alcohol solvent added more excessively than the mol number of the silver salt so as to become an excess alcohol solution; heating the excess alcohol solution in a reaction chamber at a generation temperature PT generating an aldehyde for a generation time; forming a silver core through reducing of the silver salt by the alcohol solvent and/or the aldehyde; and forming a composite silver nanoparticle having an organic coating layer originated from the alcohol solvent around the silver core.
