スケツト。 A sheet-shaped gasket used in the exhaust system of an engine, which has a laminated structure of a ceramic fiber sheet mainly composed of ceramic inorganic fibers and a graphite sheet made of graphite. The inner peripheral part located on the gas passage side is made to protrude toward the surface on which the graphite sheets are laminated, and the protruding part shields the graphite sheet from the exhaust gas passage, and the protrusion width of the protruding part is set to the side of the graphite sheet. A high temperature gasket characterized by being larger than its thickness.
