PROBLEM TO BE SOLVED: To provide a fuel injection control device properly performing a fuel injection control of an internal combustion engine for a long period of time, and preventing increase in maximum combustion pressure or deterioration in exhaust characteristics. SOLUTION: Integrated travel distance LDST of an engine loading vehicle is corrected depending on accelerator pedal manipulated variables AP, and a corrected travel distance LDSTC is calculated (S11). A travel distance correction coefficient KDST of a fuel injection time is calculated depending on the corrected travel distance LDSTC (S12). The travel distance correction coefficient KDST is set to decrease, as the corrected travel distance LDSTC increases. Correction of the fuel injection time using the travel distance correction coefficient KDST maintains an actual fuel injection amount to be an appropriate value, regardless of change with the lapse of time of fuel injection valve characteristics.
