PURPOSE:To facilitate machining and improve the atomization of fuel as well as accuracy in the quantity of injection by fixing a member having a fuel passage, a member on which a slit is formed and a member having an orifice, to a nozzle. CONSTITUTION:When a ball valve 12 is opened, a fuel passes through an annular gap 502 between a convex member 51 and a nozzle 5, and enters an eccentrically provided slit 504 of a swirler 52 from more than one fuel passage 503. Here, an eccentric passage of fuel is formed between the convex member 51 and an orifice member 53. Thereby, swirling force is given to the fuel, which is throttled by an orifice, permitting measurement, and is atomized and injected.
