Abstract
A method of manufacturing a metal gasket having a base plate and coating layers deposited thereon. A first coating layer (10) having a first vulcanizing agent is deposited on a metallic base plate (1). A second coating layer (20) is deposited on the first coating layer (10) and has a second vulcanizing agent. The first coating layer (10) and the second coating layer (20) are vulcanized with different vulcanized rates from each other. For instance, a cold type vulcanizing coating layer, which is vulcanized at an ordinary temperature, and a hot type vulcanizing coating layer, which is vulcanized at a higher temperature than the ordinary temperature, are formed, and heated at a predetermined temperature to vulcanize only the former, so that two layers having different vulcanized rates from each other are formed to provide a vulcanized layer and an unvulcanized layer on the base plate.
