This invention provides an annular metal gasket having an improved structure which is generally used in various kinds of machinery, equipment, apparatus and the like as a sealing means to be fitted in a groove or similar, wherein the degree of the elastic fatigue caused by the pressure applied to the gasket can be reduced, The fatigue limit can be raised, and the sealing performance can be assured, while any difficulty in reusing the gasket after the overhaul being eliminated. An annular metal gasket according to the present invention comprises an annulus with a gap in its outer periphery and an endless groove with a substantially C-shaped cross-section, and a resilience control member which is inserted in this gap and is engagingly supported on both edges of the gap in the annulus. Further, an annular metal gasket according to the present invention comprises an annulus formed of a plurality of different materials which are aggregated together and also is a resilience control member which is divided into a plurality of pieces and inserted in the gap in the annulus.
