To blow off flames uniformly into a combustion chamber while an air/fuel mixture in the combustion chamber can be sufficiently supplied to an ignition point, while enabling stable spark ignition of the air/fuel mixture.
An ignition plug 10 is disposed in the axial direction of the combustion chamber so that a plug cover 13 may project from a cylinder head side into the combustion chamber 3. A plurality of communication holes 15 comprise a leading-end-side communication hole 16 provided on the leading end side of the plug cover 13 projecting into the combustion chamber 3 in the axial direction, and a base-end-side communication hole 17 provided closer to the base end side of the plug cover 13 than the leading-end-side communication hole 16. The base-end-side communication hole 17 is configured so that resistance to a fluid flowing from the combustion chamber 3 to an ignition chamber 14 may be smaller than that of the fluid flowing from the ignition chamber 14 to the combustion chamber 3. The air/fuel mixture M flowing to the ignition chamber 14 from the combustion chamber 3 flows obliquely upward in the base-end-side communication hole 17.
