FUEL NOZZLE AND COMBUSTOR OF GAS TURBINE, AND GAS TURBINE

This diffusing combustion type fuel nozzle of a gas turbine is provided with: a nozzle body; a plurality of nozzle holes which extend along the axial direction of the nozzle body and are arranged along the circumferential direction of the nozzle body, and in which the center axes of the nozzle holes are inclined toward the center axis of the nozzle body at a portion of the center axis of each of the nozzle holes closer to the downstream side, in the axial direction, of the nozzle body; and a plurality of fuel supply holes that serve as fuel supply routes which extend along the axial directionof the nozzle body and which are connected to the plurality of nozzle holes for supplying fuel. The plurality of nozzle holes each have an injection port for injecting fuel to an end portion on the downstream side in the axial direction of the nozzle body. When each of the plurality of nozzle holes is projected onto a projection surface orthogonal to the center axis of the nozzle hole at the position of the center axis of
