ABSTRACT:
A metal gasket for an internal combustion engine is formed of at least one metal plate for constituting the metal gasket. The metal plate includes a hole and a bead formed around the holes for sealing the same. A thermal sprayed layer is formed integrally on and/or under the bead to locally increase the surface pressure of the bead when the bead is compressed. Thus, the surface pressure of the bead can be adjusted individually as desired.
