A cylinder head gasket of the invention is formed of a main plate extending substantially throughout the entire area of the gasket, sealing devices formed around the cylinder bores, and at least one auxiliary plate laminated over the main plate. The auxiliary plate is situated at least in an intermediate area of the main plate surrounded between the two adjacent holes corresponding to the cylinder bores. The auxiliary plate includes two edge portions extending at least partly along the cylinder bores adjacent the intermediate area, a base portion between the two edge portions, and two turning portions laminated over the respective edge portions. When the gasket is tightened, the edge portions and the turning portions provide high surface pressure around the cylinder bores. Accordingly, leakage of gas at the intermediate area is prevented.
