A metal gasket is formed by first and second metal base plates. The first metal base plate has a first main bead, and first outer and inner sub-bead sections formed outside and inside the first main bead and projecting outwardly in a direction opposite to the first main bead. The second metal base plate has a second main bead, and second outer and inner sub-bead sections formed outside and inside the second main bead and projecting outwardly in a direction opposite to the second main bead. A distance between the second outer and inner sub-bead sections is greater than that between the first outer and inner sub-bead sections. When the first and second metal base plates are assembled, the second outer and inner sub-bead sections entirely sandwich the first outer and inner sub-bead sections therebetween to substantially abut against each other at side peripheries thereof.
