<P>PROBLEM TO BE SOLVED: To provide a structure capable of controlling the fuel injection quantity more accurately than a conventional one. Ž<P>SOLUTION: A fuel injection control device 4 for controlling operation of an in-cylinder injection valve 2 for directly injecting fuel into a cylinder 11a of an internal combustion engine 1 comprises: in-cylinder pressure obtaining sections 40 and 47; and a fuel injection quantity correcting section 40. The in-cylinder pressure obtaining sections 40 and 47 obtain the in-cylinder pressure, namely, the pressure inside the cylinder 11a in operation of the internal combustion engine 1. The fuel injection quantity correcting section 40 corrects an error of the fuel injection quantity on an increase side due to a valve closing delay of the in-cylinder injection valve 2 based on the in-cylinder pressure obtained by the in-cylinder pressure obtaining sections 40 and 47.
