Abstract
A disclosed laminated sheet to be wound around an outer surface of an exhaust gas processing unit includes a first mat containing first inorganic fibers and a second mat containing second inorganic fibers, the second mat being laminated on the first mat. The average fiber length of the first inorganic fibers is larger than the average fiber length of the second inorganic fibers and the laminated sheet is to be wound around the exhaust gas processing unit such that the first mat forms an outermost layer. Development of cracks in the outer surface of the laminated sheet can be prevented by winding the laminated sheet around an exhaust gas processing unit such that the first mat faces outward.
