Abstract
A metal gasket having first and second base plates made of metal. In each base plate, at least an opening is defined and a bead is formed around the opening. The second base plate is disposed in parallel with the first base plate with the tip ends of the beads of the first and second base plates facing each other. An annular metallic shim is secured to the first base plate at the side of the bead between the inner periphery of the bead and the opening. And, a resilient sealing member is deposited on the second base plate at the side of the bead around the outer periphery of the bead. A non-vulcanized coating layer of fluoro rubber containing no vulcanizing agent may be deposited on the entire surface of the second base plate at the side of the bead. A vulcanized fluoro rubber may be deposited on the non-vulcanized coating layer at the side of the bead around the outer periphery of the bead.
