PROBLEM TO BE SOLVED: To provide a method for economically and efficiently manufacturing a single-particle powder of inorganic particles of calcium carbonate or the like dispersed as single particles excellent in the improving effect of physical constitution and plysical properties. SOLUTION: This method for taking out the inorganic particles synthesized in the aqueous system as the single-particle powder is composed of a process (1) for preparing an aqueous suspension of inorganic particles in the aqueous system, a process (2) for substituting a water medium with an organic solvent immediately after the process for preparing the aqueous suspension of the inorganic particles in the aqueous system and a process (3) for separating the single-particle powder of the inorganic particles from the organic solvent suspension of the inorganic particles obtained in the process (2).
