PROBLEM TO BE SOLVED: To provide a fuel injection valve increasing magnetic attraction force or a fuel injection valve preventing variation of fuel injection quantity with suppressing increase of manufacturing cost. SOLUTION: A non-magnetic member 14 covers an outer periphery side of a cap 100 formed between a movable core 30 and an attraction member 44 over both of the movable core 30 and the attraction member 44. The non-magnetic member 14 prevents short of magnetic flux between a valve holder 12 and a connecting member 40 and prevents leak of magnetic flux to an outer periphery side from the movable core 30 and the attraction member 44 without passing through the cap 100. The connecting member 40 is provided with a projection part 42 cylindrically extending to the movable core 30 side on the outer periphery side. The projection part 42 stores the attraction member 44 in an inner periphery side and positions the attraction member 44. The attraction member 44 is formed out of more ferromagnetic material than the connecting member 40. A spring 48 is guided in an expansion direction on at least either one of inner periphery surfaces of the movable core 30 and the attraction member 44. COPYRIGHT: (C)2007,JPO&INPIT
