Abstract
A gasket is interposed at a joining portion between two members. The gasket includes a gasket base plate having an opening through which fluid flows and a plurality of annular beads formed in a wave shape over a predetermined area extending outwardly from a hole edge of the opening; and at least one shim covering only the annular beads. The shims are laser-welded at a welding portion to cover the beads. Thus, the metal gasket does not have a pressure trace on abutting surfaces of a cylinder head.
