ABSTRACT:
A method of manufacturing a steel plate for a steel laminate gasket comprises applying a first seal coating consecutively on at least one side of a base plate in the shape substantially the same as that of an actual steel plate for constituting the gasket. After the first seal coating on the base plate is dried, the base plate is pressed or cut to form a plurality of steel plates. Each steel plate has a configuration as in the actual steel plate, an outer surface formed by the first seal coating on the entire one side thereof and a plurality of holes therein. When a steel laminate gasket is formed, the steel plate with the seal coating thereon is stacked with other steel plates so that the seal coating is located between the two steel plates.
