PROBLEM TO BE SOLVED: To provide a simple method for producing a highly monodisperse resin fine particle having a high monodispersion of narrow particle size distribution and the objective particle diameter of nanoorder. SOLUTION: In the method for producing a monodisperse fine particle (I) by discharging a dispersed phase composed of a polymerizable monomer (b) from an opening part to be connected to a continuous phase (B) flowing in a microreactor (A), making liquid drops composed of the dispersed phase dispersed in the continuous phase and polymerizing the polymerizable monomer, a uniform shear stress is applied from outside to the liquid drops to form monodisperse fine liquid drops (C) of monodispersion so that the highly monodisperse fine particle (I) having an average particle diameter of 50-500 nm is obtained.
