A fuel injection valve includes a solenoid, which is filled with low-pressure oil. The solenoid receives a biasing means and a movable member. The movable member is actuated by the biasing means and magnetic force generated by the solenoid. The movable member includes a flat-plate portion that contacts with the solenoid and departs from the solenoid. The outer circumferential periphery of the flat-plate portion has multiple notches, through which low-pressure fuel flows into to the upper side of the flat-plate portion that has an oil passage groove, through which a center portion of flat-plate portion communicates with the outer circumferential portion of flat-plate portion. Each notch has a deepest portion that is radially most recessed from the outer circumferential periphery of the flat-plate portion. The oil passage groove is apart from a deepest portion of the notches.
