Abstract
Copper-containing nanoparticles with excellent oxidation resistance is provided. The present invention relates to a method for manufacturing copper-containing nanoparticles including obtaining copper-containing nanoparticles that contain an organic component by heat treating an organic copper compound at a temperature equal to or higher than a decomposition initiation temperature of the compound and lower than a complete decomposition temperature of the compound in a non-oxidative atmosphere in the presence of an organic material containing a 1,2-alkanediol having 5 or more carbon atoms and/or a derivative thereof.
