PROBLEM TO BE SOLVED: To stably ensure an excellent sealing property, to prevent a complexity of a constitution as much as possible, and to manufacture at a low cost. SOLUTION: The metal gasket 1 is provided with a first gasket base plate 11 and a second gasket base plate 21. A stepped stopper 12 of U-shaped cross section circumferentially and continuously surrounding a combustion chamber bore 3 and a first bore bead 13 circumferentially and continuously surrounding the stepped stopper at an outer periphery side of the stepped stopper are formed on the first gasket base plate. A flat surface 21A is formed at a position superposed with the stepped stopper on the second gasket base plate, and a second bore bead 22 is circumferentially and continuously formed at a position superposed with the first bore bead. A sub-bead can be formed instead of the flat surface 21A, and an elastic member can be provided in a space formed by the stepped stopper and the flat surface 21A.
