Abstract: An inorganic fiber molded body includes an alumina fiber, an inorganic porous filler, and a colloidal silica, in which a ratio of crystalline minerals in the alumina fiber is 30% by mass or more and 80% by mass or less, the inorganic porous filler contains CaO·6Al2O3 in which a particle diameter D95, which has a cumulative value of 95% in a volume frequency particle size distribution, is 300 μm or less, and in 100% by mass of the inorganic fiber molded body, a content of the alumina fiber is 15% by mass or more and 70% by mass or less, a content of the inorganic porous filler is 20% by mass or more and 79% by mass or less, and a content of the colloidal silica is 2% by mass or more and 8% by mass or less.
