During both the valve opening and valve closing operation of this electromagnetic fuel injection valve, a movable element is operated in an idle running manner before the valve body begins to activate, and a bounding operation of the movable element that occurs during the valve opening action is suppressed, with the purpose being to improve both responsiveness and operational stability. The invention is configured so as to comprise, as a movable element which is suctioned by the magnetic core (109) of the electromagnetic fuel injection valve to open and close the valve, a first movable element (105) urged by a first spring (106) for urging in the valve-closing direction, and a second movable element (104) urged in the direction of the magnetic core (109) by a second spring (112) for urging in the valve-opening direction. |
