To provide a fuel injection control device with an injector having improved productivity, for converging an instrument error without worsening the accuracy of an injection amount in spite of less correction points.

The fuel injection control device comprises the injector 3 for selectively injecting or stopping supply fuel depending on a control signal, a control means 10 for outputting the control signal to the injector in accordance with the condition of operating an internal combustion engine 1, and an information recording medium 32 for storing predetermined inherent characteristic information. The control means 10 corrects the control signal in accordance with characteristic data mutually connecting the large injection amount side and the small injection amount side of coordinating characteristics for coordinating a designed injection amount with an actual injection amount and outputs the corrected control signal to the injector. Data on the large injection amount side out of characteristic data is obtained from data Δ1 which converges the instrument error stored in the inherent characteristic information, and the data on the small injection amount side is data Δ2-Δ1 for converging the instrument error calculated in accordance with learning data Δ2 which is first recognized with learning control during operating the internal combustion engine.
