ABSTRACT:
A metal plate of the invention is used for a metal gasket. The metal plate comprises a base plate, at least one first bead to surround an area to be sealed, and at least one second bead extending from the first bead. An intersecting portion is formed between the first and second beads. The intersecting portion is provided with a depression extending from a side of a non-high pressure area toward an inside of the intersecting portion to reduce the size of the intersecting portion. As a result, the intersecting portion of the first and second beads can provide surface pressure at least substantially equal to the rest of the portions of the first and second beads without affecting the sealing ability at a high pressure area when the beads are compressed.
