ABSTRACT:
A metal gasket for an internal combustion engine is formed of a metal plate including a base portion extending substantially throughout an entire area to be sealed, at least one hole formed in the base portion, a curved portion extending from the base portion, and a flange extending from the curved portion and disposed on a part of an upper surface of the base portion. A coating member is deposited on the flange facing the base portion and/or the base portion facing the flange. The coating member is formed of a non-thermoplastic coating material to operate as a surface pressure regulating member between the flange and the base portion to thereby regulate a surface pressure at the flange.
