The invention relates to a cylinder head gasket comprising a gasket unit ( 10 ), which has at least one through opening, particularly a combustion chamber opening ( 12 ), and which has at least two interacting gasket plies ( 18, 20, 22 ) of which one ( 18, 20 ) is provided with a flexible bead ( 26, 28 ) encircling the through opening, and the other ( 22 ) is provided with a device ( 34 ) that limits this flexibility. Said device ( 24 ) has, on opposite sides ( 34, 38 ), alternating recesses ( 30 ) and elevations ( 32 ) whereby a recess ( 30 ) is located, at least partially, opposite an elevation ( 32 ). At least a portion of the recesses ( 30 ) and of the elevations ( 32 ) have an essentially trapezoidal cross-section with sloped delimiting walls ( 36 ) extending between the adjacent recesses ( 30 ) and elevations ( 32 ) of one side ( 34 or 38 ) of gasket ply ( 22 ), and the adjacent opposite delimiting walls ( 36 ) of both sides ( 34, 38 ) delimit a web cross-section (SQ 1 ) of gasket ply ( 22 ) that is greater than or equal to the web cross-section (SQ 2 ) delimited between the opposite recesses ( 30 ) of both sides ( 34, 38 ).
