PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine accurately correcting fuel injection quantity to adjust quantity of fuel actually supplied to the internal combustion engine to a target value, securing startability, especially cold startability which requires much fuel injection quantity per onc injection, and preventing deterioration of exhaust emission. SOLUTION: Fuel injection quantity (injection actual fuel quantity QF) per unit time is calculated in real time and is integrated using fuel pressure during fuel injection. Actual fuel injection quantity is made accurately coincide with target injection quantity by adjusting injection completion timing by comparing integrated injection quantity QFS and target injection quantity TQ.
