PROBLEM TO BE SOLVED: To provide a method for producing composite spherical fine particles whose structure comprising a phenolic resin and silica is controlled, which have silica layers having proper hardness, and whose silica contents are easily controlled.;SOLUTION: This method for producing the phenolic resin/silica composite spherical fine particles is characterized by adding an aqueous solution containing an emulsion stabilizer (D) to an organic phase comprising a phenolic resin (A), a silicon compound (B) and an organic solvent (C) to invert and emulsify the organic layer phase, and then thermally curing the obtained fine particles.;COPYRIGHT: (C)2006,JPO&NCIPI
