Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fuel injection valve capable of preventing a drive coil from being deformed and the accuracy of the position relation of a spool to a magnetic cylindrical body from being lowered in a molding step for a resin material. SOLUTION: A ring part 62b projecting toward a holder 11 is formed on the spool 62 on the contact part side end 15a of a housing 15, and brought into contact with the holder 11. In the molding step for the resin material, the filled resin material is prevented from flowing into a gap between the inner peripheral part of the spool 62 and the outer peripheral part of the holder 11. Consequently, an injector 10 capable of preventing the drive coil 64 from being deformed and the accuracy of the position relation (concentricity) of the drive coil 64 to the holder 11 from being lowered in the molding step for the resin material can be provided.
