The present invention relates to oxidation resistant copper nanoparticles, and to a method for producing the same, which includes the steps of: preparing a first solution composed of a solvent, a polymer, and an organic acid; stirring the first solution to produce a first stirred solution; mixing the first stirred solution, a copper precursor, and a first reducing agent to produce a second reactant solution; mixing a second reducing agent with the second reactant solution to produce a third reactant solution; and collecting copper nanoparticles separated from the third reactant solution, which is a very simple process performing the reactions at a normal temperature under atmospheric conditions to produce copper nanoparticles, and an eco-friendly method firstly applying a watery solvent so as to achieve mass production of copper nanoparticles only by mixing solutions. In particular, the copper nanoparticles according to the present invention may have excellent oxidation resistant properties to prevent them from being oxidized for three months or more even when preserved at a normal temperature under atmospheric conditions.
