PROBLEM TO BE SOLVED: To provide a fuel feeding device for an internal combustion engine capable of adjusting the amount of fuel injected from a fuel injection valve while reducing the consumption of energy required for securing a fuel feeding capability. SOLUTION: This device is provided with a fuel pump 52 for pumping the fuel from a fuel tank 51, a fuel injection valve 5 for injecting the fuel discharged from the pump 52 into the internal combustion engine 100, and a control means 30 for adjusting a fuel injection amount by varying the valve opening time TQ of the injection valve 5. Besides, a pressure accumulating tank 53 and a fuel pressure detection means 54 for measuring the fuel pressure in the accumulating tank 53 are provided between the pump 52 and the injection valve 5. The control means 30 controls the driving times TP and TT of the pump 52 according to the behavior of fuel pressure detected by the pressure detection means 54 to drive the pump intermittently in such a way that the fuel stored in the accumulating tank 53 is secured within a range of prescribed pressures, and also controls the valve opening time TT of the injection valve 5 according to the behavior of fuel pressure.
