Abstract
A metal gasket exhibiting an excellent seal effect on external foreign matter, such as salt water, and having low reaction force when required sealing pressure is low. The metal gasket, which is sandwiched between a pair of housings to seal the internal space of the housings and prevent entrance of external foreign matter between the housing and the gasket, has a straight portion, where the entire surface from an inner peripheral edge portion to an outer peripheral edge portion is a planar shape. A bent bead portion, directed obliquely outward and contacting one of the housings, is integrally provided in the outer peripheral edge portion of the straight portion. The bent bead portion functions as both an inward seal sealing the internal space and an outward seal preventing the entrance of external foreign matter between the housing and the gasket.
