| 1. A method of producing metal nanoparticles, the method comprising:
forming copper nanoparticles from a copper precursor by using a reducing agent under a solvent including a primary amine;
and
forming a metal thin layer having high reduction potential on the surface of the copper nanoparticles, with a metal precursor
which has higher reduction potential than copper.
