PROBLEM TO BE SOLVED: To provide an inorganic fiber board having high density, compatibilized light-weight and flexural strength, improved surface properties and good recyclability. SOLUTION: This inorganic fiber board is produced by bonding inorganic fibers with a binder and has a density of >=150 kg/m<3> . The ratio of inorganic fiber in the board is 50-95 wt.% and >=30 wt.% of the inorganic fiber is glass wool produced by centrifugal spinning method and having an average fiber length of 100-6,000μm.
