A metal gasket for an internal combustion engine is formed of at least one metal plate extending substantially throughout an entire area to be sealed. The metal plate includes a hole to be sealed, and a bead projecting outwardly from the first metal plate to surround the hole. A concave is formed inside the bead to extend inwardly from an outer surface of the metal plate. A sealing material is disposed in the concave to project outwardly from the outer surface of the first metal plate. Thus, even if a foreign material is disposed on the bead, the sealing ability of the gasket is not substantially affected.
