Abstract:
A metal gasket which enables improvement of sealing properties by making sufficient compression of a full bead possible even if elastic coating is formed along the full bead. In the gasket (1) having a full bead (13), formed on a metal substrate (10), having a mountain-shaped protruding surface formed on one side in a thickness direction and a valley-shaped recessed surface formed on the other side in the thickness direction, elastic coating (20) is formed on the whole surface of the protruding surface of the full bead (13), and the elastic coating (20) is formed on the recessed surface of the full bead (13), except a slit-shaped elastic coating-free section (14) along a bottom section (13a) of the recessed surface.
