Abstract: In an apparatus for continuously manufacturing microspheres, a dispersed phase (O) is supplied to a chamber 27 for the dispersed phase inside of a bulkhead member 26 via a supply port 23. Thereafter, the dispersed phase enters into a gap 31 between a plate 22 via a supply port 29 in a base 25. The dispersed phase which enters into the gap 31 grows microspheres (particles) having a certain diameter while passing through a microchannel 33 by pressure applied by, for example, a pump, and is mixed with a continuous phase (W), so that microspheres are produced. The thus-produced microspheres float or are suspended in the continuous phase without needing any particular external force in response to their specific gravity, allowing the microspheres to be generated and withdrawn from a withdrawal port 32 at a significantly reduced pressure in comparison to conventional methods and apparatus.

Then, the dispersed phase is made into a particle having a predetermined diameter by a microchannel (24) in passing through this boundary section (21), thereby forming an emulsion (E) in which the dispersed phase (O) of the predetermined diameter is dispersed in the continuous phase (W).
