Abstract
A steel laminate gasket comprises a plurality of thin steel plates to be stacked one after another, and devices for identifying the position of the steel plates formed on the steel plates where no sealing ability is affected. When the steel plates are stacked in the proper order, the devices form a stepped portion with different height relative to a predetermined horizontal plane of the gasket. Consequently, a user can notice the proper order of assembly of the gasket.
