Zusammenfassung:Provided is a fine particle production apparatus and a fine particle production method capable of easily obtaining surface treated fine particles. The fine particle production apparatus produces fine particles using feedstock by means of a gas-phase process. The apparatus includes a treatment section configured to transform the feedstock into a mixture in a gas phase state by means of the gas-phase process, a feedstock supply section configured to supply the feedstock to the treatment section, a cooling section configured to cool the mixture in a gas phase state in the treatment section using a quenching gas containing an inert gas, and a supply section configured to supply a surface treating agent to fine particle bodies in a temperature region in which the surface treating agent is not denatured, the fine particle bodies being produced by cooling the mixture in the gas phase state with the quenching gas.
