PROBLEM TO BE SOLVED: To provide a fuel injection quantity control device of an internal combustion engine capable of supplying a desired quantity of fuel to an engine in the middle of warming-up. SOLUTION: A flank angle sensor 20 detects engine revolutionary speed, and a pressure sensor 26 detects pressure of a suction pipe. An ECU 30 computes basic injection time with warming-up completion time as a standard in accordance with engine revolutionary speed and suction pipe pressure. The ECU 30 judges whether a suction system of the engine 1 is warmed up or not at the time of low temperature starting of the engine 1. Additionally, the ECU 30 sets a correction factor to the quantity increasing side small as intake air quantity passing a suction pipe 10 becomes larger as basic fuel injection quantity per hour is larger and corrects fuel injection quantity to the quantity increasing side by using the correction factor.
