Fuel Injection Valve

Provided is a fuel injection valve which can be easily processed and can realize sufficient atomization while suppressing spreading of spray. In the fuel injection valve according to the present invention, when a nozzle plate and a first direction - in which fuel is sprayed are projected onto a virtual plane perpendicular to a central axis line of the fuel injection valve along an opening and closing valve direction of a valve body and a first orthogonal coordinate system having an X passing through a center O of the nozzle plate and along the first direction - and a Y axis passing through the center O of the nozzle plate and perpendicular to the X axis is virtualized on the virtual plane, an introduction passage - is inclined so that a straight line segment - connecting between a central point - of an upstream side end portion and a center Oa- of an inlet opening surface of a fuel injection hole - is positioned on the Y axis side with respect to a straight line - passing through the central point - and the center O of the nozzle plate
