PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of effectively absorbing noise in the vicinity of a noise generation source without changing the outline dimension of the fuel injection valve. SOLUTION: A circular part 15 having bubbles is attached to the inside of a pipe 14 and between a valve seat 12 having an injection port and an armature 5 with a valve element 11 connected. Thereby, impact sounds generated respectively between the valve element 11 and the valve seat 12 and between the armature 5 and a core 4 can be absorbed by the circular part 15, and noise can be reduced. Further, the circular part 15 is mounted by being pressure-fitted to the pipe 14, thereby, the stiffness of the whole valve is improved, and the valve can be produced at a low cost.
