Abstract
A metal gasket is formed of a metal base plate for sealing between two members. The metal gasket has a bead around a cylinder bore and a bead around a fluid hole on the metal base plate. Coatings are applied on both surfaces of the beads, respectively. When the metal gasket is tightened, strong sealing surface pressures are locally generated at sealing line portions of the beads. The coatings are applied only on other portions except for the sealing line portions.
