Summary:The object of the disclosure is to provide a method for efficiently producing fine particles with low crystal growth of the raw material components, in particular fine particles with a plurality of raw material components in a highly complexed state and having low crystal growth, without blockage of the nozzle. The method of the disclosure for producing particles includes injecting a good solvent solution that includes a good solvent and one or more raw material components dissolved in the good solvent, with a nozzle into a precipitating poor solvent that has been heated to a temperature higher than the boiling point of the good solvent, to evaporate the good solvent solution and precipitate a plurality of particles, and running a cleansing poor solvent through the nozzle before starting and after completing injection of the good solvent solution into the precipitating poor solvent.
