PURPOSE: To provide an electromagnetic fuel injection valve by which fuel can be sufficiently atomized with a comparatively simple structure.

CONSTITUTION: A gas passage from a gas supply port 10 is arranged in a fuel passage from a fuel supply port 1, and bubbles can be mixed in fuel injected from a fuel injection hole 9. These bubbles expand and burst when the fuel is injected into an intake air pipe from the fuel injection hole 9, and atomize the fuel sufficiently. Thereby, since the fuel can be atomized effectively with a simple structure, a combustion condition of an engine can be sufficiently improved.
