Abstract: In a fuel injection valve, it is possible to obtain spray in which the penetrating force of injected fuel is suppressed. The fuel injection valve includes a valve seat that forms a gap with a valve body, the gap allowing fuel to pass therethrough, and multiple injection holes that are located further downstream from the gap. The fuel to which pressure is applied flows out from the injection holes. When the flow velocity of the fuel in the gap formed between the valve body and the valve seat is indicated by meters per second, the flow velocity is set to be greater than a value obtained by multiplying the square root of the pressure applied to the fuel by 28. In this manner, the flow velocity in the gap increases, and flow velocity distribution inside the injection hole is uniformized, thereby suppressing an increase in penetration.
