Abstract
In a nozzle plate of the present invention, a part of fuel flowing out from a fuel injection port of a fuel injection device is atomized by colliding with an interference body, is rapidly bent in a flowing direction, and collides with the fuel that is flowing straight through a nozzle hole and an orifice to make the fuel that flows straight through the nozzle hole and the orifice turbulent. The orifice includes a corner portion which is defined by an outer edge portion of the interference body and has a pointed shape without roundness at a part of an opening edge. The corner portion makes an end portion of a liquid film of the fuel passing through the orifice into a pointed shape for ease of atomization by friction with air.
