Abstract
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 plateand 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 Xpassing through a center Oof the nozzle plateand along the first direction-and a Yaxis passing through the center Oof the nozzle plateand perpendicular to the Xaxis 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 Yaxis side with respect to a straight line-passing through the central point-and the center Oof the nozzle plate
