ABSTRACT:
A metal gasket of the invention is used for an internal combustion engine. The gasket is basically formed of one metal plate extending substantially throughout an entire area of the engine to be sealed. The gasket includes a plurality of cylinder bores and a plurality of liquid holes. At least one corrugated bead is formed in the metal plate to be located around at least one of the liquid holes without forming corrugated beads around all of the liquid holes. The corrugated bead is formed at a portion where a surface pressure sufficient to seal around a liquid hole is not obtained.
