PROBLEM TO BE SOLVED: To provide a fuel injection valve provided with a low-priced structure for adjusting a pushing force for seating a valve member onto a vale seat. SOLUTION: This fuel injection valve is provided with a valve body 29 having the valve seat 29a, a nozzle needle 26 having an abutment part 26c capable of abutting/separating on/from the valve seat 29a and opened/closed by abutting/ separating the valve seat 29a and the abutment part 26c on/from each other, an energizing spring 24 for energizing the nozzle needle 26 in the valve closing direction, and an adjusting pipe 21 as an adjusting bush for adjusting the energizing force of the energizing spring 24. The adjusting pipe 21 is a split pin having a split part 21a and possible to be reduced in the radial direction, and the cross section of the adjusting pipe 21 is formed into an ellipse, and the split part 21a is formed in the peripheral wall of the short diameterΦB side of the ellipse.
