  "textContent": "An electromagnetic fuel injection valve wherein a central pipe (27) part has satisfactory mechanical strength and an intermediate portion of the pipe part is surely made non-magnetic is provided. The electromagnetic fuel injection valve has a core (3) surrounded by a solenoid coil (6). A valve housing (1) is disposed forward of the core (3). The core (3) and the valve housing (1) are connected through a thin-walled portion (35). The wall thickness of the thin-walled portion (35) is smaller than the wall thickness of the core (3) and that of the valve housing (1). The core (3) and the thin-walled portion (35), together with the valve housing (1), are formed in an integral structure. The thin-walled portion (35) has a sufficient wall thickness to provide satisfactory mechanical strength. The thin-walled portion (35) is modified into a high-hardness non-magnetic portion by a carbulizing treatment.",
