摘要

PROBLEM TO BE SOLVED: To provide a metal nanoparticle colloid, a metal nanoparticle and a multiple metal nanoparticle colloid which is high-purity and high-concentration, and can be used in such a state as to be dissolved in various solvents widely ranging from hydrophilic solvent to hydrophobic solvent, and to provide a method of inexpensively manufacturing a multiple metal nanoparticle. SOLUTION: The concentration of the metal nanoparticle in the colloid is enhanced by repeatedly binding metal nanoparticle to a moving body 26 of a fluidized film-like surfactant without dissolving the metal nanoparticle into a solvent to collect the metal nanoparticle while putting the metal into a movable state by evaporation 24 or the like in a reduced pressure environment or in a vacuum 21.
