Fine spherical mesoporous silica fine particles can be obtained, SDA can be extracted and removed in a liquid phase without high-temperature firing, and chemical modification to the surface can be easily performed. Provided is a method for producing mesoporous silica fine particles capable of obtaining mesoporous silica fine particles. Tetraalkoxysilane, an alkoxysilane having an amino group, a quaternary ammonium salt cationic surfactant, a polyhydric alcohol having two or more hydroxyl groups, and a mixture containing water, and tetraalkoxysilane and Spherical silica nanoparticles having mesopores on the surface are produced by co-hydrolyzing an alkoxysilane having an amino group in the presence of an alkali.
