SOLUTION: This cylinder head gasket 1 comprises a first gasket substrate 2 having a plurality of combustion chamber bores 4 formed thereon and a second gasket substrate 3. A stepped stopper 2A having a U-shaped cross section and surrounding the outer circumference of each of the combustion chamber bores 4, and a first bore bead 2B surrounding the outer circumference of a stepped stopper are formed on the first gasket substrate. A second bore bead 3B superposing with the first bore bead is formed on the second gasket substrate. The first bore bead and the second bore bead are gathered into one line, respectively, in an area where the adjacent combustion chamber bores are close to each other. The width of the first bore bead is set smaller than the width of the second bore bead. The height of the first bore bead is set lower than the height of the second bore bead. Thus, the first bore bead can be arranged even in the area where the adjacent combustion chamber bores are close to each other, and good followability can be secured.
