A metal gasket (A) of the invention is used for a cylinder head gasket or a pipe connecting gasket. The gasket is basically formed of a single metal plate (A10) having a base portion extending substantially throughout an entire area to be sealed, and includes a bead protecting portion (A11) extending outwardly from the front surface and a sealing bead (A12) adjacent to the bead protecting portion (A11). The bead protecting (A11) portion and the sealing bead (A12) are formed in the metal plate (A10). The bead protecting portion (A11) has no substantial compressibility, but the sealing bead (A12) has a compressibility. Thus, when the metal plate (A10) is compressed, the bead protecting portion (A11) provides a surface pressure without substantial resiliency, and the sealing bead (A12) provides a surface pressure with resiliency and is protected from being completely compressed by the bead protecting (A11) portion. The gasket (A) can be made thin. <IMAGE> |
