A metal laminate gasket of the invention is installed in an internal combustion engine having at least one hole to be sealed. The gasket is basically formed of a first metal plate and a second metal plate situated over the first metal plate. The first and second metal plates respectively include first and second base portions extending substantially throughout an entire area of the engine, first and second curved portions to define first and second holes, and first and second flanges extending from the first and second curved portions. The second hole has a diameter greater than an outer diameter of the first flange so that the first flange is located inside the second curved portion when the first and second plates are assembled. The thickness of the first plate is greater than the thickness of the second plate and less than a double thickness of the second plate. Thus, when the gasket is compressed, the second flange provides surface pressure greater than that at the first flange to securely seal around the hole of the engine away from the first flange.
