PROBLEM TO BE SOLVED: To provide a production method where hyperfine metal nanoparticulates with a uniform particle diameter of about 10 nm can be produced at high reproducibility in a short time. SOLUTION: An Au ion-containing sodium tetraaurate (III) aqueous solution is prepared, so as to be an original liquid, further, using a surfactant (produced utilizing 4 m mol of a polyethylene glycol monosterate solution as an original liquid) and ultrapure water, so as to be a raw material solution, and electron beam energy of 10 MeV is emitted, thus metal nanoparticulates with a uniform particle diameter are produced.
