Cylinder head gasket

A cylinder head gasket (1) is formed of a single metal base plate (10) for sealing between a cylinder head and a cylinder block of an internal combustion engine. The cylinder head gasket (1) has a primary sealing portion (S1) including a grommet (11, 14) or shim (14) around a cylinder bore, and a secondary sealing portion (S2) outside the primary sealing portion. The secondary sealing portion (S2) is formed of a bead (12) and a foamed coating layer (22) coated on one side or both sides of the bead to cover at least a portion of the bead in a belt shape.
