Abstract
In a fuel injection device including a body portion that forms an injection hole through which a fuel is injected, the body portion includes an inlet-channel-forming portion that is connected to an inflow port of the fuel in the injection hole and forms an inlet channel which is a fuel flow channel, and an outlet-channel-forming portion that is connected to the inlet channel and an outflow port of the fuel in the injection hole, and forms an outlet channel that is a fuel flow channel. A surface roughness of the outlet-channel-forming portion is larger than a surface roughness of the inlet-channel-forming portion.
