If the amount is less than 20% by weight, the thickness of the bulky inorganic fiber mat may not be reduced, and if it exceeds 40% by weight, it may take a long time to dry. In addition, from the viewpoint of reducing the amount of exhaust gas components, the amount of resin is preferably 8% by weight or less.

Thereby, the thickness of the inorganic fiber mat can be further reduced, and the drying time can be shortened. Further, it is preferable to dehydrate the impregnated resin solution before performing the pressure drying. This increases the drying efficiency.
