Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel injection control device that can further reduce collision noise of members while reliably opening a valve body in valve opening operation of a fuel injection valve.SOLUTION: The fuel injection control device reduces a driving current to be applied to a coil 14 till a second collision signal that shows a collision of a movable core 17 with a stationary core 13 is input after a first collision signal that shows a collision of the movable core 17 with the valve body 15 is input.SELECTED DRAWING: Figure 1 【課題】燃料噴射制御装置において、燃料噴射弁の開弁動作において弁体を確実に開放しつつ部材同士の衝突音をより低減可能とする。【解決手段】可動コア１７の弁体１５への衝突を示す第１衝突信号が入力されてから、可動コア１７の固定コア１３への衝突を示す第２衝突信号が入力されるまでの間に、コイル１４に印加する駆動電流を低減させる。【選択図】図１
