PURPOSE: A cylinder head gasket is provided to secure stable sealing state by appropriately sealing an inferior processed part of a cylinder block so as to improve sealing performance of the gasket. CONSTITUTION: Beads(5,7) are formed on an upper plate(1) and a lower plate(3) on an oil channel sealing part of a cylinder head gasket to protrude downward. Shapes of the beads on the upper plate and the lower plate are the same. The beads comprise linear upper horizontal sections(9) formed on both ends thereof, linear inclined sections(11) sunken toward a center, and linear lower horizontal sections on centers thereof. The bead formed on the lower plate and the bead formed on the upper plate exert force to apply efficient sealing pressure even when an inferior processed part is formed on an upper side of a cylinder block is formed near engine oil channels so as to prevent leakage of engine oil.
