To provide a method for producing a fine particle which is excellent in collection rate of a fine particle to be obtained.

The method for producing a fine particle generates an arc discharge 3 between an electrode 2 and a sample 4 to evaporate the sample, and obtains the fine particle, wherein an atmosphere for generating the arc discharge 3 is a mixed gas atmosphere where helium and hydrogen are mixed and a nitrogen concentration is 0.5 vol% or less.
