A metal gasket for use between heads and blocks of an internal combustion engine in which such gasket is composed of a beaded plate and a stopper plate placed one on top of the other. The metal gasket has an opening corresponding to the cylinder hold of the engine. The metal gasket has an annular stopper formed by folding back the periphery of the opening in the stopper plate. The metal gasket also has a stepped part along the outer periphery of the stopper. This stepped part projects toward the side of the gasket on which the stopper is formed. The metal gasket also has a spacer layer formed between the stopper and an annular pressure receiver of the stopper plate. The metal gasket also has a rubber coating layer formed at least on that side of the stopper plate opposite to the side on which the stopper is formed.
