PROBLEM TO BE SOLVED: To provide a fuel injector capable of effectively suppressing generation of pollutant substances while preventing degradation of durability of a gas turbine engine. SOLUTION: The fuel injector K comprises a pilot fuel injection unit 10 and a main fuel injection unit 20. The pilot fuel injection unit 10 comprises an inner fuel chamber forming body 11, an inner oil film forming body 12 surrounding the inner fuel chamber forming body 11, an inner air flow passage 13, and an inner wall 14 surrounding the inner oil film forming body 12 to form an outer periphery of the inner air flow passage. The fuel injected from an inner fuel chamber 11a of the inner fuel chamber forming body 11 onto an inner surface of the inner oil film forming body 12 is formed into oil film and fed to the downstream side on the inner surface of the inner oil film forming body 12, and discharged in a film from a downstream side tip 12a. The fuel discharged in the film is atomized by the air flow of the inner air flow passage 13, and fed to a combustion range R. COPYRIGHT: (C)2004,JPO&NCIPI
