Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a silicic acid having a uniform layer of a silylating agent which method overcomes such the defects on a well- known technology level as causes the problem of not only corrosion, but also the additional cost for particular materials and improved purification as well as the environmental pollution and/or highly expensive exhaust gas treatment and the exhaust gas purification treatment. SOLUTION: The method for manufacturing the silicic acid having the uniform layer of the silylating agent comprises the silylation of a silicic acid with the organosiloxane constituted with a unit A expressed by the formula (I): R13SiO1/2and a unit B expressed by the formula (IIa): R12SiO2/2and/or the formula (IIb): R1SiO3/2and/or the formula (IIc): SiO4/2.
