AbstractA steel laminate gasket of the invention is installed in an internal combustion engine having at least one hole therein. The gasket comprises a first plate having at least one first hole therein corresponding to the hole of the engine, and a second plate having at least one second hole. The first plate is provided with a base portion, at least one curved portion adjacent the first hole, and at least one flange situated parallel to the base portion. The base portion, curved portion and flange are integrally formed together. At least one side wall is formed on one of the base portion and the flange adjacent the curved portion to surround the first hole. The thickness between the flange and base portion inside the side wall is greater than the thickness between the flange and base portion outside the side wall so that an embossed portion is formed around the first hole. The second plate is situated adjacent the first plate so that the second plate does not pile the flange of the first plate.
