A monolayer metal gasket is disclosed, which may be kept against deformation around a bolt hole and further made stable in sealing stress around a gas hole between mating surfaces of confronting components. A first extra thickness around the gas hole is provided by turning back a part of a metallic sheet on a major flat of the metallic sheet, with leaving a space open between them to form a folded construction having elasticity. A second extra thickness around a bolt hole is a closely layered construction of nearly rigid body little to be deformed. When the monolayer metal gasket is squeezed between the mating surfaces of the confronting components, a clearance between the mating surfaces may be regulated to a preselected distance by virtue of the second extra thickness that is little to be deformed.
