PROBLEM TO BE SOLVED: To provide a fuel injection valve inhibiting drop of quality and injection performance. SOLUTION: This fuel injection valve 10 includes a thin wall part 23 which is a magnetic reluctance part 23 at a sidewall of a pipe 21 formed in a tubular shape. A fuel passage 27 is formed at an inner circumference side of the pipe 21. A movable core 51 reciprocating in an axial direction and a valve member 40 are held in the fuel passage 27, and a fixed core 54 is press-fitted and fixed at a base end side of the movable core 51. A coil 62 generating magnetic flux is provided at an outer circumference side of the pipe 21. A housing 63 magnetically connecting a first magnetic part 22 and a second magnetic part 24 of the pipe 21 is disposed at a further outer circumference side thereof. A plurality of press-fit parts 58 press-fitted and fixed in the pipe 21 are formed on an outer wall 57 of the fixed core 54. Some of the press-fit parts 58 overlap in an axial direction with a connecting part 65 connecting to the first magnetic part 22 in the housing 63. COPYRIGHT: (C)2011,JPO&INPIT
