A method for manufacturing copper nanoparticles is provided to produce nanometer-size copper nanoparticles having a narrow particle size distribution and good dispersibility in commercial quantity. A method for manufacturing copper nanoparticles includes the steps of: (a) preparing a mixture solution comprising a copper salt, a dispersing agent, a reducing agent, and an organic solvent; (b) heating the mixture solution to 30-50 ‹C and stirring the mixture solution; (c) applying microwaves to the mixture solution; and (d) lowering the temperature of the mixture solution to obtain copper nanoparticles. The (d) step includes the steps of: centrifuging the mixture solution to separate copper nanoparticles; and washing and drying the separated copper nanoparticles. Further, the reducing agent is selected from a group consisting of NaH2PO2, N2H4, HCl and NaBH4.
