Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cylinder head can concentrically and efficiently cool a support wall of an ignition plug, and a portion corresponding to a combustion chamber center top part of a lower surface wall, and can improve engine performance. SOLUTION: A hanging wall 20 hanging from an upper surface wall 1 of a water jacket 7 and extended to a width direction is provided, and widthward both ends 20a and 20b of the hanging wall 20 is positioned on an upstream side of a flowing direction of cooling water compared to a width direction center part 20c. A downward opening notch 21 is formed on a portion on the most downstream side with respect to the cooling water flowing direction of the width direction center part 20c of the hanging wall 20, and the support wall 11 of the ignition plug 10 is positioned on the cooling water flowing direction downstream side of the notch 21.
