The out-orifice is provided around a periphery of an inlet opening thereof with an inlet circumferential edge with which a flow of fuel to be ejected from a pressure control chamber (15) via the out-orifice is swirled so that turbulent flow is forcibly formed. Then, the turbulent flow is maintained until the fuel is ejected. Dimensions of the out-orifice satisfy the formulas, R / D",
