Claim Text:
1. A method for producing microparticles, comprising the steps of: preparing a microparticle raw material solution by dissolving at least one microparticle raw material in a solvent by using a high speed agitator; and mixing said microparticle raw material solution with at least one separating solution to separate said microparticle raw material in a thin film fluid formed between at least two processing surfaces, which are disposed in a position facing each other, and operable to approach to and separate from each other, at least one of which rotates relative to the other, thereby separating the microparticles, comprising the sub-steps of: directly controlling an introduction velocity of one of the microparticle raw material solution and the separating solution, which are introduced into the space between the at least two processing surfaces, so as to control a particle diameter of separated microparticles.
