PROBLEM TO BE SOLVED: To provide a cylinder injection type gas fuel engine without causing deterioration in fuel economy or exhaust gas performance. SOLUTION: In the gas fuel engine 100 injecting and supplying gas fuel into a cylinder, an annular slit-like nozzle hole 204 or a plurality of nozzle holes 206 facing on a combustion chamber 105 is formed in a nozzle hole ring 200. The gas fuel supplied from a gas fuel injection valve 120 is injected and supplied into the cylinder through the annular slit-like nozzle hole 204 or the plurality of nozzle holes 206. thereby enabling homogeneous lean combustion even under a low-speed, low-load condition.
