Cylinder head gasket

A cylinder head gasket (1, 1A) is provided with a half bead (12) formed along a substantial external outline of a gasket around cylinder bores (2), water holes (3), and the like of the gasket. It is possible to enhance compression resistance of the half bead, thereby preventing creep and obtaining excellent sealing performance. The cylinder head gasket includes a plurality of holes (2, 3, 4) to be sealed, and a continuous half bead (12) formed around all or at least more than two of the holes to be sealed (2, 3 4). The continuous half bead (12) has at least one portion (14) formed in a waveform in a plan view.
