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. The 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. The thicknesses of the coatings at the sealing line portions are formed to be thinner than those of the other portions.
