PROBLEM TO BE SOLVED: To provide copper fine particles which are hard to receive the influence of a scale factor, and in which particle diameters are balanced in spite of the fineness thereof, and which are hard to receive the influence of oxidization even if being exposed to an ordinary temperature environment, and to provide a method for forming the particles. SOLUTION: By the production method where a compound of copper and nickel is dissolved into a reaction solvent dissolved with one or more kinds of linear alcohols in which the number of carbons is 6 to 10 and one or more kinds of organic compounds in which the number of molecules is 200 to 400, and thereafter, an organic ammonium hydroxide salt solution is added, the copper-nickel nanoparticles in which the constituting ratio of copper in the central part is high, and a nickel-copper alloy is exhibited in the circumference are produced.
