PROBLEM TO BE SOLVED: To substantialize stable combustion over the entire driving region of a gas engine equipped with an ignition plug and a fuel injection valve for oil fuel injection inside a sub chamber, and to improve durability of the ignition plug by preventing deterioration by high temperatures of the ignition plug in high load region of the engine. SOLUTION: The combustion control device for the gas engine is equipped with the ignition plug for igniting and combusting sub chamber gas inside a sub chamber, and the fuel injection valve for injecting oil fuel inside the sub chamber. The device is provided with an electromagnetic valve for opening/closing a sub chamber gas supplying passage, an engine driving state detection means for detecting the driving state of the engine, and a controller for supplying or shutting off fuel gas to the sub chamber by opening/closing the electromagnetic valve according to the detected value of the engine driving state, and controlling operation or shutting down of operation of the ignition plug and shutting down and operating of fuel injection systems including the fuel injection valve.
