PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of accurately learning a non-injection current carrying time without worsening a driving feeling. SOLUTION: The fuel injection control device learning the non-injection current carrying time until fuel is actually injected after instructing fuel injection to an injector, has an injection instructing means for instructing fuel injection to the injector (step S33), an engine state determining means for determining whether a change has occurred to the engine operating state after the lapse of a reference time after instructing the fuel injection (step S36), a reference time updating means for updating the reference time by adding a predetermined time to the reference time when no change has occurred to the engine operating state (step S32), and a non-injection current carrying time learning means for learning the time obtained by subtracting the predetermined time from the reference time at that time, as the non-injection current carrying time (step S38).
