A cylinder head gasket includes a first gasket base plate 11 at a cylinder head side, a second gasket base plate 12 at a cylinder block 2 side, a shim 15 that adjusts the gasket thickness, and a pressure increasing plate 16 that increases the surface pressure at the side of periphery portions of the cylinders 3. In the first and second gasket base plates 11, 12, full beads 11a, 12a are swollen at the side of periphery portions of cylinders 3, and half beads11b, 12b are swollen at a site outward of the full beads 11a, 12a. The full beads 11a, 12a of the first and second gasket base plates 11, 12 are formed so that top portions 11c, 12c of the full beads 11a, 12a face each other at positions that are opposite to each other in the up-down direction. The shim 15 and the pressure increasing plate 16 are sandwiched between the top portions 11c, 12c.
