Fuel injection control device

The invention provides a fuel injection control device which promotes good atomization of fuel through correcting an injection amount in fuel injection. An injection amount calculation part (50) calculates the injection amount every preset time period. A control part (10) corrects the calculated injection amount in fuel injection performed by the fuel injection device (8) through the newly calculated injection amount. A target value for stopping fuel injection is preset to wholly injected angles (R1,R2) in reference to a crankshaft angle. The control part (10) starts fuel injection at a time point when injection of the calculated injection amount is finished at the wholly injected angles (R1,R2). The control part (10) performs basic injection and additional injection in one circle of an internal combustion engine. The additional injection is performed after the basic injection. The additional injection is performed according to an amount which is obtained through subtracting an injection finishing amount gene
