Abstract: PROBLEM TO BE SOLVED: To rapidly produce a mixture wherein substantially monodisperse particulates of a dispersion phase are distributed homogeneously enough in a continuous phase. SOLUTION: An apparatus 1 for producing the fine particles comprises two tubes, an outer tube 11 and an inner tube 12 coaxially disposed with each other. The tip 21a of the inner tube 21 is separate from the top 11b of the outer tube 11 by a relatively long distance. While Fluid II flows in the inner tube 21 toward its tip 21a, Fluid I flows as a continuous phase in the outer tube 11 toward its top. Fluid II discharged from the tip 21a of the inner tube 21 can be turned into almost spherical droplets 3 having a desired diameter and surrounded by Fluid I in the outer tube 11, by controlling pumps 14, 24 each according to the command of a controller 31 to make Fluid I and Fluid II flow at a proper flowing velocity in the outer tube 11 and the inner tube 21 respectively.
