Summary:PURPOSE:To reduce operation noise even when the weight of the valve body of an electromagnetic fuel injection valve is not reduced. CONSTITUTION:A recessed part 1b is provided on the bottom part 1a of an electrifying connector 1 so that an electrifying pin 2 is surrounded by the recessed part, and that the electrifying connector 1 and a harness side connector 3 are not brought into direct contact with one another on the inside of the recessed part 1b by means of a gap between them. The recessed part 1b is reversibly large with a very small annular bottom part 1a left on the front end circumferential part of the harness side connector 3. The contact area between the electrifying connector on the valve side and the front end of the harness side connector is reduced, thus, narrowing a transmission route to the outside, and operation noise is thus reduced.
