PROBLEM TO BE SOLVED: To provide a fuel injection control device of an internal combustion engine capable of solving inconveniences accompanied by an ignition delay period by changing the fuel injection pressure according to deviation of the in-cylinder pressure from a conformable value. SOLUTION: In the fuel injection control device 13 applied to an internal combustion engine 1 in which the fuel injection timing into a cylinder from a fuel injection valve 9 is controlled based on a target value corresponding to the conformable value of the in-cylinder pressure determined according to the operational state, the present value of the in-cylinder pressure is acquired, and the fuel injection pressure of the fuel injection valve is controlled in the direction for canceling any change of the ignition delay period according to the deviation based on the deviation of the present value from the conformable value.
