Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a copper nanoparticle in which oxidation resistance and joinability are consistent though the achievement of their consistence has been difficult by the conventional technique. SOLUTION: The method for producing a copper nanoparticle comprises: a stage where citric acid is added to a solvent; a stage where a copper source is dissolved into the solvent, so as to produce copper ions; and a stage where a reducing agent is added to the solvent while flowing an inert gas, so as to reduce the copper ions, and a copper nanoparticle containing citric acid on the surface is formed. In this invention, by beforehand dispersing a protective agent suppressing oxidation into the solvent, the produced copper nanoparticle is swiftly protected with the stable protective agent, so as to suppress oxidation.
