PROBLEM TO BE SOLVED: To provide a fuel spraying device of a gas turbine engine capable of improving ignitability, flame stability, and especially combustion stability at low loads in a combustor to which a complex combustion system is adapted wherein two systems of combustion systems of a diffusive combustion system and lean combustion system are combined. SOLUTION: The fuel spraying device U of the gas turbine engine is provided with a first fuel spraying part 10 for spraying fuel for diffusive combustion, and a second fuel spraying part 20 provided so as to surround the first fuel spraying part 10 for spraying fuel for premix combustion. An air curtain forming part 30 for forming an air curtain defining an outer edge of a diffusive combustion area is provided between the first fuel spraying part 10 and the second fuel spraying part 20.
