PROBLEM TO BE SOLVED: To provide a manufacturing method of nanoparticles with a particle size of 200 nm or less that is capable of easily manufacturing an inorganic nanoparticle colloidal solution and nanoparticles of a multi-component alloy or multi-component compound of an arbitrary composition with excellent recovery efficiency and with good quality. SOLUTION: The nanoparticle of 200 nm or less is manufactured by radiating high energy light of less than 400 nm to a raw material liquid. The raw material liquid prepared by dissolving platinum chloride (IV) hexahydrate (H<SB>2</SB>Pt(IV)Cl<SB>6</SB>-6H<SB>2</SB>O) in ethanol (C<SB>2</SB>H<SB>5</SB>OH) is used when the nanoparticle to be manufactured is a Pt nanoparticle.
