PROBLEM TO BE SOLVED: To provide a fuel injection control unit of an internal combustion engine for preventing vibration in a vehicle, or the like, having an internal combustion engine performing a cylinder cut-off operation by making identical the injection conditions of an actual fuel for each cylinder for performing fuel injection in the fuel injection for performing the cylinder cut-off operation, based on the operating state of an engine load, or the like, of the internal combustion engine, and hence making identical the combustion conditions of the fuel between the cylinders. SOLUTION: The fuel injection control unit of the internal combustion engine having a plurality of cylinders has a cylinder cut-off means for reducing the number of working cylinders for injecting fuel, based on the operating state of the internal combustion engine. The fuel injection control unit detects the engine rotational speed of the internal combustion engine in the working cylinders (S101), and controls the amount of fuel injection in the working cylinders, based on the engine rotational speed of the internal combustion engine in the working cylinders (S102) or controls a fuel injection period.
