PROBLEM TO BE SOLVED: To provide a manufacturing method for a polymer particle wherein the manufacturing yield and CV value (standard deviation (μm) of microparticle) of the particle size are improved through inhibition of coalescence or aggregation of a seed particle at manufacturing of a polymer such as a polyorganosiloxane particle used as a spacer for a liquid crystal display device or as a standard particle. SOLUTION: In the manufacturing method for the polymer particle, a monomer having an alkoxyl group and/or a hydroxyl group is reacted in the presence of a catalyst to form the seed particle. Then, an aqueous solution containing the monomer or its hydrolysate is added to the seed particle to grow the seed particle. Here, the formation and the growth of the seed particle are performed in a reaction vessel of an inverted-cone shape. COPYRIGHT: (C)2005,JPO&NCIPI
