A cylinder head gasket 1 is sandwiched between a cylinder head 2 and a cylinder block 3 with a cylinder bore 4 and includes a substrate 10 with a combustion chamber hole 14 drilled at a position of the cylinder bore 4, and seal plates 11 to 13, the substrate 10 and the seal plates are stacked on one another. Fixation members 21 and 22 are secured to the substrate around a periphery of the combustion chamber hole. The seal plate includes an engagement hole 23 formed therein and with which the fixation members are engaged. The engagement hole is engaged with the fixation members. The fixation members are sandwiched between the cylinder head and the cylinder block. The cylinder head and the cylinder block can be firmly coupled together via the fixation members. This allows deformation of the cylinder block caused by explosion pressure in an engine to be suppressed. As a result, possible degradation of sealability can be prevented.
