PROBLEM TO BE SOLVED: To provide a fuel injection control device which estimates precisely a fuel injection amount, and corrects thereby precisely the fuel injection amount in response to the deterioration state of a fuel injection valve. SOLUTION: This fuel injection control device for controlling the fuel injection valve includes a valve opening timing detecting means for detecting the valve opening timing of the fuel injection valve, a fuel injection amount estimating means for estimating the fuel injection amount, based on the valve opening timing, and a correction control means for comparing an estimated value of the fuel injection amount with a preliminarily found initial value of the fuel injection amount, and for correction-controlling the fuel injection amount, when the relation therebetween satisfies a correction executing condition.
