In order to provide a ceramic fiber board which does not emit smoke and does not cause a problem of shedding of particles even when used in a high-temperature environment, the invention provides a method of producing a ceramic board which uses ceramic fibers containing Al2O3 and SiO2 as a raw material, in which a mixed liquid (Na2Ox3SiO2) of SiO2 sol and water glass is used as an inorganic binder, in which weight ratio in terms of the solid contents of SiO2 and water glass is SiO2: 89 to 35% and water glass: 11 to 65%.
