Claim:
1. A method for producing a microparticle wherein the method comprises at least two steps as following: (I) a first step of precipitating a seed microparticle in a thin film fluid formed between at least two processing surfaces which are disposed in a position they are faced with each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, whereby discharging a fluid which contains the seed microparticle thus precipitated as a discharge fluid, and (II) a second step of growing the precipitated seed microparticle in the discharge fluid whereby obtaining a prescribed microparticle, wherein in the second step, into a tubular vessel having an introduction port in one end and a discharge port in other end, the discharge fluid is introduced from the introduction port, whereby growing the seed microparticle in the tubular vessel, and wherein the first step and the second step are executed continuously.
