PROBLEM TO BE SOLVED: To provide a cylinder head gasket 1 having superior sealability and capable of being inexpensively manufactured. SOLUTION: This cylinder head gasket is composed of a foundation plate 11 made of an aluminum material and having plural bores 11a corresponding to a combustion chamber, and bore seals 12 made of a rubber elastic material and mounted around bores 11a of the foundation plate 11. The bore seals 12 are fitted in grooves 111U, 111L formed along the circumference of the bores 11a on both faces of the foundation plate 11, seal lips 121U, 121L are projected to the thickness direction of the foundation plate 11, and running-off deformation permitting spaces S1 in compressing the bore seals 12 are formed respectively between the seal lip 121U, 121L and the groove 111U, 111L. The seal lips 121U, 121L get good results in self-sealing function by the combustion gas pressure in the combustion chamber.
