PROBLEM TO BE SOLVED: To provide a production method for an inorganic spherical body having substantially uniform particle size with good productivity over a long period, and an apparatus for the same. SOLUTION: In the production method for the inorganic spherical body, an aqueous liquid containing an inorganic compound is extruded through a plurality of fine holes formed in one partition wall, into an organic liquid flowing in a laminar flow state at a rate of 0.001-2 m/s in a passage partitioned by the partition wall, and a W/O emulsion is formed with the organic liquid as a dispersion medium and the aqueous liquid containing the inorganic compound as a dispersion phase, then the aqueous liquid in the emulsion is solidified to form the inorganic spherical body. A metallic sheet with a surface subjected to water-repellent treatment is used as the partition wall with the lot of fine holes formed thereon. COPYRIGHT: (C)2005,JPO&NCIPI
