PROBLEM TO BE SOLVED: To provide a fuel injector for a gas turbine engine. SOLUTION: This fuel injector 40 has three pipes 60, 62, 64 forming a flow passage passing through the injector and accompanying. In this typical embodiment, an upstream side part of each pipe has inlets 68, 70, 72 projected from the outside surface 66 of a flange 42 and accompanying. A first flow passage (passing through the first pipe 60) is a pilot flow passage, and terminates at an outlet opening 80. A second flow passage (passing through the second pipe 62) is a main liquid fuel flow passage, and terminates in the circular arrangement of an outlet opening 82 formed at the outside of a pilot opening 80. A third flow passage (passing through the third pipe 64) is a gaseous fuel flow passage, and terminates in the circular arrangement of an outlet opening 84 formed at the outside of the opening 82.
