Zusammenfassung:	To provide a fuel injection control device of an internal combustion engine which can perform accurate fuel injection control taking into consideration a variation of each fuel injection valve at the execution of a half-lift mode of the fuel injection valve.SOLUTION: A fuel injection control device of an internal combustion engine comprises a fuel injection amount correction part for correcting a fuel injection amount of a first fuel injection valve of a first cylinder in a fuel injection amount correction state that the first fuel injection valve of the first cylinder injects fuel a plurality of times in a half-lift mode, and a fuel injection valve of a cylinder other than the first cylinder injects fuel in a full-lift mode.SELECTED DRAWING: Figure 7 【課題】燃料噴射弁のハーフリフトモードの実行時において、各々の燃料噴射弁のばらつきを考慮した高精度な燃料噴射制御を可能とする内燃機関の燃料噴射制御装置を提供する。【解決手段】第一気筒の第一燃料噴射弁がハーフリフトモードで複数回、燃料を噴射し、前記第一気筒以外の気筒の燃料噴射弁がフルリフトモードで燃料を噴射する燃料噴射量補正状態の下で前記第一気筒の前記第一燃料噴射弁の燃料噴射量を補正する燃料噴射量補正部を備えた。【選択図】図７
