(57) [Summary] [Purpose] The present invention relates to a method for producing a pyrolytic metal oxide filler having a low structure. [Structure] In this method, a metal oxide agglomerate and an aggregate produced by a thermal decomposition method selected from silicon oxide, aluminum oxide, zirconium oxide or titanium oxide are subjected to a dry grinding step, in which the thermal decomposition is performed. Contacting the metal oxide produced by the method with force in a stirring zone. |
