Abstract
A metal laminate gasket of the invention is used for an internal combustion engine. The gasket is formed of a plurality of metal plates for constituting the metal laminate gasket, wherein each metal plate has a hole corresponding to a fluid hole of the engine. A bead is formed on one of the metal plates to surround the hole for sealing therearound. Outer surface layers are coated on outer surfaces of the metal laminate gasket, and at least one inner surface layer is coated on at least one of inner surfaces of the metal plates. The outer surface layers are formed of a material containing rubber to closely contact the gasket to the engine parts, and the inner surface layer is formed of a material containing resin to provide sliding ability between the metal plates. The gasket can securely seal between the engine parts.
