PROBLEM TO BE SOLVED: To obtain a method for manufacturing a fine monodisperse solid particle having a diameter of not less than several μm. SOLUTION: A method for manufacturing a fine monodisperse solid particle by polymerizing a reactive monomer comprises (1) a step of producing an emulsion by pressurizing a dispersive-phase composition containing a reactive monomer and dispersing the dispersive-phase composition in a continuous phase via a microchanel, (2) a step of producing a suspension of the solid fine particle by polymerizing the emulsion and (3) a step of recovering the solid fine particle by removing the continuos phase from the suspension.
