A metal gasket which is clamped between the two joining surfaces and has at least one hole for fluid, includes a bead for sealing the two joining surfaces, the bead surrounding the at least one hole for fluid, each of which allows openings for fluid to be communicated with each other, the openings being provided in the respective joining surfaces. The metal gasket further includes a convex portion, the tip of which abuts one of the joining surfaces, is provided in the vicinity of a portion of the beads abutting the other joining surface.
