    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing inorganic spherical bodies each having such a large particle diameter that the average particle diameter becomes 100 μm or more. SOLUTION: In the method for producing inorganic spherical bodies having an average particle diameter of 100-1,000 μm, the inorganic spherical bodies are obtained through a process for forming a W/O-type emulsion by dispersing an aqueous liquid containing a specified inorganic compound into an organic liquid, a process for forming a metal oxide by hydrolysis of a metal alkoxide on the outer shell part of each droplet of the aqueous liquid containing the inorganic compound by adding the metal alkoxide to the W/O-type emulsion, and a process for forming the inorganic spherical bodies by solidifying the aqueous liquid containing the inorganic compound in the W/O-type emulsion after the formation of the metal oxide.
