    • Disclosed herein is a fuel injection control apparatus for an internal combustion engine, capable of opening and closing accurately a valve of the fuel injector even when the quantity of injection required is small and a pulse duration of a driving pulse signal to the fuel injector is short.A fuel injector pulse width computing unit 9a calculates, from the operational state of the internal combustion engine and the fuel pressure detected by a fuel pressure sensor, pulse width of a pulse signal which drives the valve of the fuel injector. After an valve-opening command has turned on and a high valve-opening current for opening the fuel injector valve has been supplied from a high-voltage source to the fuel injector, a fuel injector driving signal waveform command unit 9b discharges the current and supplies from a low-voltage source a small hold current Ih2 that allows the fuel injector to maintain the valve-open state. Also, during the time from supply of the valve-opening current to an arrival at the value of the hold current Ih2, after the elapse of a previously assigned rapid-discharge starting time Tsy from the turn-on of the valve-opening command, the fuel injector driving signal waveform command unit 9b rapidly discharges the current until the hold current Ih2 has been reached.
