A metal gasket of the invention comprises at least one metal plate including at least one fluid hole, a main bead extending around and adjacent to the fluid hole, and at least one auxiliary bead situated at an area away from a tightening device of the gasket. The auxiliary bead diverges from a part of the main bead, extends along the main bead and again merges to a part of the main bead. Therefore, an area adjacent the tightening device is sealed by the main bead, and the area away from the tightening device is sealed by the main bead and auxiliary bead to thereby provide equal sealability around the fluid hole when the gasket is tightened.
