PROBLEM TO BE SOLVED: To provide nanoparticle manufacturing method and separation method by which the amount of a solvent used for removing surplus organic matters can be minimized. SOLUTION: This nanoparticle manufacturing method comprises: a first step of preparing a mixture in which nanoparticles having organic matter therearound and surplus organic matter are intermingled; and a second step of separating, in the mixture, the nanoparticles and the surplus organic matter. The second step comprises: a step A of heating and liquefy the mixture; and a step B of cooling the resulting liquid slowly to solidify it again in such a state that a layer where the nanoparticles are unevenly distributed and a layer where the surplus organic matter is unevenly distributed are separated.
