A metal gasket excellent in sealing performance and capable of sealing with a small pressing force. The metal gasket comprises at least one metal sheath with C-shaped cross-section and a ring elastic core surrounded by the metal sheath and the metal gasket is served for sealing with aid of the contact with the sealing face tightened by exerting a force in the axis center direction, wherein the metal sheath has the worked portion with a locally thin cross-section over the whole length, and when the metal sheath is exerted with a force and deformed, the deflection in the axis direction of the metal sheath due to concentrated stress on the thin worked portion causes to form projections at the both sides of the deflection which projections are pressed onto the sealing face.

[ What is claimed is:] [1.] A process for preventing leakage of fluid by use of a metal gasket having at least one metal sheath with a C-shaped cross-section comprising:providing on the periphery of the at least one metal sheath a thin-walled portion;positioning the metal gasket adjacent to a sealing face with the thin-walled portion facing the sealing face,applying a force to the metal-gasket via the sealing face,causing in response to the applied force a deflection in the thin-walled portion and a formation of projections at both sides of the deflection, andpressing the projections onto said sealing face to prevent leakage of fluid.
