摘要：A cylinder head gasket 1 includes at least one first seal plate 11 held between a cylinder head 2 and a cylinder block 3 having a cylinder bore 4, and the first seal plate 11 includes a combustion chamber hole 13 bored at a position of the cylinder bore 4 and a first full bead 11a surrounding the combustion chamber hole. In the first seal plate 11, a first step 11b U-shaped in section is formed at a position surrounding the combustion chamber hole outside of the first full bead 11a, and a filler 21 is charged in a recessed portion of the first step. Since the cylinder head and the cylinder block can be firmly connected via the step 11b, deformation of the cylinder block by explosion pressure of an engine can be suppressed, and thereby, reduction in sealing performance can be prevented.
