Abstract
An object of the present invention is to provide a fuel injection valve that is made superior in atomization performance by preventing an influence of minute deformation occurring when an orifice plate is assembled to a nozzle body, thereby reducing fuel leakage from a swirling passage to increase the strength of a swirl flow. The valve includes a valve body openable and closable to jet fuel; a nozzle body having a valve seat surface capable of coming into contact with the valve body to block the jet of fuel; and an orifice plate disposed downstream of the valve seat surface and having a plurality of fuel injection holes adapted to jet swirl fuel. The nozzle body has an end face portion with a downwardly convex inclined surface.
