A metal laminate gasket for an internal combustion engine is formed of a first metal plate, a second metal plate situated under the first metal plate, and a plurality of annular plates. The first metal plate includes a base portion, a plurality of curved portions extending from the base portion to define first holes, and a plurality of flanges extending from the curved portions to be disposed over the base portion. Each annular plate is situated between each flange and the base portion, and has at least one flat section and at least one partial bead section disposed at an intermediate portion between the first holes. The partial bead does not extend throughout an entire length of the annular plate. Therefore, when the gasket is tightened, the surface pressure at the intermediate portion can be increased to securely seal thereat. In case the rigidity of a cylinder head is not strong, the gasket is especially useful.
