PROBLEM TO BE SOLVED: To prevent deterioration in the accuracy of a magnetic pipe, and lower the manufacturing cost of a solenoid fuel injection valve. SOLUTION: An injection port 14 is opened and closed by a valve element 17, and an armature 23 is connected to the rear end of a movable body 19, to which the valve element 17 is fixed, and a fixed core 26 is arranged inside the magnetic pipe 10, at a position opposite to a rear end surface of the armature 23. The valve element 17 is energized in the closing direction by a coil spring 28, and a solenoid coil 32 is arranged outside the magnetic pipe 10. The magnetic pipe 10 as a whole is formed of a magnetic material.
