PURPOSE:To obtain a uniform fuel injection mist flow by inclining a fuel passage outwardly with respect to a valve axis line and forming an intake passage on the side wall of a mixed gas guide pipe, in the captioned device equipped with the mixed gas guiding pipe which mixes the fuel which flows out from the jet port of a fuel passage with air and jets out said mixture. CONSTITUTION:An electromagnetic fuel injection device body 5 is equipped with a fuel passage 1 which jets out the fuel 9 introduced through a solenoid valve 8 operated by an electromagnetic coil 7 and whose top edge is formed into an injection port 4, and the fuel jetted out from the jet port 4 is mixed with air, and the mixture is jetted outside from a mixed gas guiding pipe 6. In this case, the fuel passage 1 is formed into outwardly inclined form with respect to a valve axis line, and can jets fuel in the form of swirl flow into the mix gas guiding pipe 6. Since a negative pressure state is generated in the guiding pipe 6 by the swirl flow, the outside air can be inhaled into the guide pipe 6 without using air pump, etc., by forming an intake passage 2 on the side wall of the guide pipe 6.
