To provide a fuel injection valve capable of performing characteristics necessary for reducing the injection time.
The fuel injection valve comprises a first movable core 40 to be moved to the fixed core 20 side in a state being slide-guided by a housing 10, a second movable core 50 to be moved to the fixed core 20 side so as to be contacted with the first movable core 40 from the side opposite to the fixed core 20 in a state with a radial direction clearance 90 formed with respect to the housing 10, a valve member 30 having a shaft part 32 penetrating through the movable cores 40, 50, a first projection part 34 to be contacted with the first movable core 40 from the fixed core 20 side, and a second projection part 36 to be contacted with the second movable core 50 from the side opposite to the fixed core 20, a first elastic member 60 for energizing the valve member 30 to the side opposite to the fixed core 20, and a second elastic member 70 for energizing the first core 40 to the fixed core 20 side and energizing the second movable core 50 to the side opposite to the fixed core 20 for forming an axial direction clearance 92 between the movable cores 40, 50 in a state with energization to a coil 81 stopped.
