PROBLEM TO BE SOLVED: To provide a method for producing spherical silicone resin fine particles, by which the spherical silicone resin fine particles having an average particle diameter of 0.5 to 20μm and having excellent uses in many fields can profitably be obtained at a lower cost than that by conventional methods. SOLUTION: This method for producing spherical silicone resin fine particles having an average particle diameter of 0.5 to 20μm is characterized by (1) collectively charging (b) an anionic surfactant-containing an aqueous solution adjusted to pH 0.5 to 3.0 into (a) a methyltrimethoxysilane partial hydrolysis condensate mixture comprising methyltrimethoxysilane partial hydrolysis condensates and methyltrimethoxysilane under stirring, (2) stirring the partial hydrolysis condensate mixture until to be transparently dissolved, and (3) stirring the obtained solution at a low speed in such an extent as not precipitating fine particles until to produce the fine particles.
