Abstract
A metal gasket is used for an internal combustion engine, preferably as a manifold gasket. The gasket is formed of a plurality of metal gasket sections, and at least one metal connecting section situated between two gasket sections adjacent to each other to connect the same. Each gasket section has a sealing hole to be sealed and a sealing device situated around the sealing hole. At least one through hole is formed in the connecting section. The through hole allows the connecting section to easily deform to absorb deformation of the gasket due to expansion and contraction of the engine. The gasket with the deformable connecting section can be easily and accurately formed.
