Zusammenfassung: | To provide a binder containing inorganic fiber molded body enabling fiber scattering to be suppressed in a case of high basis weight and low binder amount.SOLUTION: The present invention provides a binder containing inorganic fiber molded body formed by making a binder contained in an inorganic fiber molded body. Basis weight of the inorganic fiber molded body is more than 2600 g/m2. Content of the binder is 0.01 pts. mass or more and 2.24 pts. mass or less with respect to the inorganic fiber molded body 100 pts. mass. When performing a shaking test to put the binder containing inorganic fiber molded body of 50 mm square in a sieve having opening of 4 mm and shake the sieve by a vertically reciprocal shake method under condition of amplitude of 2 mm, shaking speed of reciprocating 3000 times/minute, and shaking time of 10 minutes, weight loss rate of the binder containing inorganic fiber molded body before and after the shaking test is 1.0% or less.SELECTED DRAWING: None
