PROBLEM TO BE SOLVED: To provide a fuel injection valve improving response of a movable iron core by making valve close delay small, performing accurate injection even if injection quantity is small and having small variation among products. SOLUTION: A fixed iron core is divided into a first fixed iron core 6a in an upstream side and a second fixed iron core 6b in a downstream side by a pipe 5. The first fixed iron core 6a is composed of magnetic material of high electric resistivity such as a green compact magnetic material. The second fixed iron core 6b is composed of magnetic material excellent in corrosion resistance such as electromagnetic stainless material. Consequently, large eddy current is not generated in the first fixed iron core 6a at a time of valve close. COPYRIGHT: (C)2007,JPO&INPIT
