Abstract
A metal laminate gasket is formed of at least three metal plates, i.e. first to third metal plates assembled together. A connecting portion is formed for partially connecting the first and second metal plates. The third metal plate has an opening located at a position facing the connecting portion for receiving the connecting portion therein. Thus, local pressure formed at the connection portion when the gasket is tightened is eliminated.
