PROBLEM TO BE SOLVED: To provide a fuel injection device wherein a cylindrical member is easily mounted to a fixed core. SOLUTION: The cylindrical member 12 has a first magnetic member 13, a non-magnetic member 14 as a magnetic resisting member, and a second magnetic member 15 successively arranged from an fuel injection side. A valve member 20 is a bottomed cylindrical hollow, and seatable on a valve seat 18a formed on an inner peripheral wall of a valve body 18. When the valve member 20 is separated from the valve seat 18a, the fuel is injected from an injection hole 19a. The fixed core 30 is cylindrical, and mounted and fixed to the cylindrical member by being press-fitted inside of the non-magnetic member 14 and the second magnetic member 15 of the cylindrical member 12. The fixed core 30 is mounted at a side contrary to the injection side with respect to the movable core 22, and faced to the movable core 22. The fixed core 30 also acts as a locking member for locking the movable core 22. COPYRIGHT: (C)2004,JPO
