Abstract
Provided are a fine particle manufacturing apparatus and a fine particle manufacturing method, which manufacture smaller fine particles. The fine particle manufacturing apparatus has: a raw material supply unit that supplies raw materials for producing fine particles into a thermal plasma flame; a plasma torch in which the thermal plasma flame is generated and the raw materials supplied by the raw material supply unit is evaporated by the thermal plasma flame to form a mixture in a gaseous state; a plasma generation unit that generates the thermal plasma flame inside the plasma torch; and a gas supply unit that supplies quenched gas to the thermal plasma flame, wherein the gas supply unit supplies the quenched gas with time modulation of the supply amount of the quenched gas.
