Zusammenfassung:	PURPOSE:To thin the thickness of the title catalyst and to enhance strength thereof by impregnating ceramic paper with a mixture of titania sol and silica sol and thereafter drying and calcining this ceramic paper and then carrying vanadium oxide thereon and forming the denitration catalyst. CONSTITUTION:Silica/alumina-based or alumina-based ceramic fiber is manufactured to sheets and thereby ceramic paper is obtained. This ceramic paper is impregnated with a mixture of titania sol and silica sol and then dried and calcined. A denitration catalyst is formed by carrying vanadium oxide on the obtained ceramic paper with solid held thereon. As the mixing ratio of the mixture of titania sol and silica sol, the value of (SiO2/(TiO2+SiO2))X100 SiO2 mixing degree is regulated to
