Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an organic-inorganic hybrid material comprising a hydrogen bonding polymer and silica, and method of manufacturing the same; and in particular to provide a new organic-inorganic hybrid material having the same appearance and bulk as precipitated silica, and method of manufacturing the same. SOLUTION: The organic-inorganic hybrid material includes silica and the hydrogen-bonding polymer, wherein the pore volume having the pore diameter of 3 nm-10 μm measured by a mercury porosimeter is ≥0.6 ml/g. The method for manufacturing the organic-inorganic hybrid material includes reacting an alkali metal silicate with an acidifying agent under the presence of water and the hydrogen bonding polymer while maintaining a pH4-9, and precipitating a reaction product.
