Abstract: The housing includes a first cylinder part having a first end connected to a nozzle, a second cylinder part having a first end connected to a second end of the first cylinder part and forming a magnetic throttle part in at least a part of the second cylinder part in an axial direction, a third cylinder part having a first end connected to a second end of the second cylinder part, and a fuel passage formed inside the first cylinder part, the second cylinder part, and the third cylinder part so as to communicate with injection holes and guide the fuel to the injection holes. A yoke has a cylindrical shape, of which the first end side is connected to the first cylinder part and the second end side is connected to the third cylinder part, and is provided on a radially outer side of the housing such that an axial force is generated in the first cylinder part and the third cylinder part in a direction in which the first cylinder part and the third cylinder part approach each other.
