PROBLEM TO BE SOLVED: To provide a cylinder head gasket with high durability, by securely fixing relative positions of a plurality of laminated gasket plates. SOLUTION: The cylinder gasket is interposed between a cylinder block in which a cylinder is formed and a cylinder head in which a combustion chamber is formed, and is constituted of a laminated body 10s formed by laminating a head-side gasket plate 21, a block-side gasket plate 22 and a shim plate 23. The laminated body 10s has cylinder forming holes 10a, 10b, 10c, calking parts 15, 16 on a side adjacent to the cylinder, and calking parts 17, 18, 19 on a side separated from the cylinder. The calking parts 15, 16 on the side adjacent to the cylinder are formed in a shape of a square recess, and are provided with cutouts and stress relaxation through-holes formed to face each other. The calking parts 17, 18, 19 on the side separated from the cylinder are formed in a shaped of a square recess, and are provided with cutouts and stress relaxation through-holes formed to face each other.
