Claims

[Claims for Utility Model Registration] 1. A substrate is provided by forming a combustion chamber hole in an elastic metal plate, and the substrate is provided with a bead that surrounds the combustion chamber hole and compensates for and absorbs the distortion of the metal plate due to thermal stress. A composite gasket characterized by having heat-resistant resin layers laminated. 2. The heat-resistant resin layer is laminated in contact with a first heat-resistant resin layer interposed between the substrate and the first sub-plate, a folded edge of the first sub-plate, a second sub-plate, and the substrate. The composite gasket according to claim 1, which is a heat-resistant resin layer comprising a second heat-resistant resin layer interposed between a third sub-plate and a second heat-resistant resin layer. 3. The composite gasket according to claim 1, wherein the heat-resistant resin layer is a heat-resistant resin layer interposed between two substrates with the tops of the beads oriented in the same direction.
