Abrégé
To provide a process for producing inorganic spheres having a substantially uniform particle size with high productivity. In a process for producing inorganic spheres, which comprises a step of injecting an alkaline aqueous liquid containing an inorganic compound into a laminar flow of an organic liquid containing a surfactant through micropores to form a W/O type emulsion, and a step of solidifying droplets of the aqueous liquid containing an inorganic compound in the W/O type emulsion by an acid to form inorganic spheres, as the organic liquid, one which is brought into contact with an acid in a state of the W/O type emulsion or after separated from the W/O type emulsion, or one which is brought into contact with the aqueous liquid and then separated and recovered, is used.
