<p>PROBLEM TO BE SOLVED: To provide a low-cost fuel injection valve having small uneveness in performance, manufactured in a machining process, an assembling process or the like wherein influence of external force is reduced without increasing a cost, having a small difference between individuals without causing magnetic distortion to a magnet core 24, and allowing improvement of accuracy and parallelism between an armature 45 and the magnet core 24. SOLUTION: In this valve, the magnet core 24 and a core installation body 41 are integrated together by welding or the like such that one side of the magnet core 24 is a free end. The core installation body 41 for installing the magnet core 24 and the magnet core 24 are integrally fixed in a fixing end (an upper circumferential part 24D) of the magnet core 24, while an end part (an attraction face 24A) of the magnet core 24 opposite to the fixing end is set to the free end.</p> |
