Abstract
The present invention provides metal nanoparticles, containing copper core and thin layer of precious metals enclosing the core to prevent oxidization of copper, in which manufacturing the metal nanoparticles is economical efficiency because of increased copper content and since such metal nanoparticles contain a metal having high electrical conductivity such as silver for a thin layer, they can form a wiring having better conductivity than copper and there is little concern that silver migration may occur.
