PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine, producing an effective reduction of harmful components of exhaust gas by shortening a time from starting control to reaching a stable feedback condition for quickening transition to the stable condition. SOLUTION: The fuel injection control device for the internal combustion engine comprises an O<SB>2</SB>sensor 1 and feedback control means 20 for feedback controlling the injection amount of a fuel to be supplied to the internal combustion engine in accordance with a signal output therefrom. The feedback control means 20 performs feedback control so that a feedback gain at starting feedback control which gives an operation constant for performing feedback control by the time when an air-fuel ratio becomes an optimum condition at starting feedback control has a larger value than a feedback gain in a normal state which gives an operation constant for performing feedback control in a stable condition, on the basis of change-over between the feedback gain at starting the feedback control and the feedback gain in the normal state.
