Abstract
A fuel injection valve includes a valve seat portion, a nozzle hole plate, and a valve member. The valve seat portion has an inner circumferential surface including a valve seat. The nozzle hole plate is disposed at a downstream side of a fuel passage of the valve seat. The nozzle hole plate has a nozzle hole for injecting fuel flowing out from the fuel passage. The valve member seats on the valve seat to close the fuel passage and unseats from the valve seat to open the fuel passage. Diameter of the inner circumferential surface decreases as approaching to a downstream side. The nozzle hole of the nozzle hole plate is formed so that length of radial outside of the nozzle hole with respect to a shaft center of the fuel injection valve is smaller than that of radial inside of the nozzle hole.
