Abstract

Provided is a fuel injection valve capable of stably injecting a fuel formed into a thin film. The fuel injection valve includes: a valve seat including a fuel path and a valve seat portion therein; a valve member including an abutment portion configured to sit on the valve seat portion, for opening and closing the fuel path through separation and contact of the abutment portion away from and with the valve seat portion; and a fuel chamber brought into communication with the fuel path, in which: the fuel chamber includes slit-like injection holes for injecting a fuel; and each of the injection holes has a slit-like shape for making fuel flows to collide against each other in a long axis direction of each of the injection holes to form a liquid film in a direction crossing the long axis direction.
