Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for treating the surface of mesoporous silica which can be suitably used for producing a surface-modified mesoporous silica having low permittivity and excellent in dispersibility in an organic solvent. SOLUTION: The method comprises a modification step in which a hydroxy group on the surface of the mesoporous silica is allowed to react with a surface-treating agent to chemically bond a hydrophobic functional group with the hydroxy group. The surface treatment is performed in a powder or paste form, wherein the mesoporous silica is mixed with the surface-treating agent which is not diluted with a solvent or diluted to a solution of 50 mass% or more.
