An object of the present invention is to provide a conductive paste which can be sintered at a lower temperature than conventional ones, particularly at a temperature of about 200 ° C. to reduce the resistance. In a conductive paste in which ultrafine metal particles are dispersed in an organic solvent, the ultrafine metal particles are (RA) n -M (where R is a hydrocarbon group having 10 or more carbon atoms, A is COO, OSO 3 , SO 3 or OPO 3 , M is silver, gold or white metal, and n is the valence of M.) A solution obtained by dissolving or dispersing a metal salt in an organic solvent for synthesis. It is synthesized by irradiating with a microwave and has a metal core composed of a metal component derived from a metal salt and an organic component derived from the metal salt and covering the periphery of the metal core.
