Abstract
A particle producing method is provided including bringing a material into contact with a compressible fluid to prepare a melt of the material, and discharging the melt from a vibrated through hole to form particles of the melt. A particle producing apparatus is also provided including a discharger to discharge the melt. The discharger includes a storage to store the melt, at least one through hole disposed on the storage, and a vibrator to vibrate the through hole. The particle producing apparatus further includes a particle forming member defining a space within which the discharged melt is formed into particles and a pressure controller controlling a pressure difference between the space and an inside of the storage so that the discharged melt is formed into a columnar melt and the columnar melt is constricted and separated into particles.
