Provided is a highly biosoluble inorganic fibrous refractory molded article that exhibits desired heat resistance without reducing expensive ceramic fibers, alumina powders and silica powders, and has reduced manufacturing costs and product prices. An inorganic fibrous refractory molded body comprising a material comprising 2 to 95% by mass of rock wool, 2 to 95% by mass of inorganic powder having a needle-like crystal structure, and 3 to 32% by mass of a binder, and preferably the needle-like crystal structure. Inorganic powder having an average length of 1 to 3000 µm, an inorganic fiber refractory molded article having an aspect ratio of 1 to 1000, and more preferably, an inorganic powder having the acicular crystal structure is a walllastite powder or a sepiolite powder. It is a fibrous refractory molded body. |
