Beschreibung
Zusammenfassung:	A metal gasket containing a metal plate (1) having an opening portion (2) and having a seal bead (4) having a bent cross-sectional shape formed along the opening portion (2) in order to suppress a variation in the height of the seal bead (4) due to a tensile stress generated in the outer periphery of the seal bead (4) in the molding of the seal bead (4) is provided with a lightening hole (5) extending along the outer periphery of the seal bead (4), in which the distance between the lightening hole (5) and the seal bead (4) is constant.
