摘要:
In a fuel injection valve having a nozzle hole plate wherein a nozzle hole is formed, the nozzle hole is formed with a flow path cross-section having an oval shape that has long axes and short axes, and the nozzle hole is formed having a tapered shape in which a flow path sectional area becomes larger from an entry-side open end portion toward an exit-side open end portion. The nozzle hole is formed such that a second angle that is an intersecting angle of opposing nozzle hole inner wall surface portions in an oblique section along the short axes of the entry-side open end portion and the exit-side open end portion, is greater than a first angle that is an intersecting angle of opposing nozzle hole inner wall surface portions in a longitudinal section along the long axes of the entry-side open end portion and the exit-side open end portion.
