PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine capable of correcting fuel injection time to inject fuel of appropriate quantity even if pressure in an intake pipe changes during fuel injection operation. SOLUTION: In the fuel injection control device for the internal combustion engine provided with an injector 3 controlling fuel pressure constant in relation to atmospheric pressure, an injector control part driving the injector to inject fuel from the injector 3 during injection time determined in relation to various control conditions, the injector control part is constructed to monitor pressure in the intake pipe after the injector 3 starts fuel injection operation, and to calculate correction quantity of injection time in relation to pressure difference between atmospheric pressure and newly detected pressure in the intake pipe to correct injection time by calculated correction quantity when variation exceeding a set value is detected in monitored pressure in the intake pipe.
