摘要

[Problem] To provide an apparatus and method for manufacturing a metal nanoparticle dispersion with which a metal nanoparticle dispersion can be manufactured without using expensive reagents or equipment, and to provide a method for manufacturing a metal nanoparticle support, metal nanoparticles, a metal nanoparticle dispersion, and a metal nanoparticle support. [Solution] This apparatus for manufacturing a metal nanoparticle dispersion is characterized in comprising: a jetting part for jetting a metal-salt solution or dispersion in which a metal salt has been dissolved or dispersed in a first liquid; a voltage-impressing part for applying a voltage to the jetting part and electrifying the metal-salt solution or dispersion; and a potential-difference-forming means for forming a potential difference between a second liquid in which the metal-salt solution or dispersion has been dispersed and the electrified metal-salt solution or dispersion, causing droplets of the metal-salt solution or dispersion to be jetted from the jetting part, and causing the second liquid to attract the droplets.
