Abstract:
1. A method for manufacturing a sheet member of a catalytic converter, the method comprising: preparing a laminated sheet by laminating precursors containing inorganic fibers, the laminated sheet having a first surface and a second surface opposite to each other and substantially perpendicular to a direction of thickness of the laminated sheet; forming unevenness, containing projecting portions and depressed portions, on at least the first surface of said laminated sheet; firing the laminated sheet to form said sheet member; impregnating an organic binder into said sheet member; and applying a heat compression drying treatment to said sheet member while pressing a press mold having a contact surface provided with a predetermined uneven profile so that the projection portions and the depressed portions of the unevenness of said sheet member have a maximum height difference, h, wherein h satisfies the relationship of about 0.4 mm≦h≦9mm.
