PROBLEM TO BE SOLVED: To provide a fuel nozzle for a gas turbine combustor that is excellent in durability and strength reliability.SOLUTION: A fuel nozzle for a gas turbine combustor jets fuel into a combustion chamber of a gas turbine combustor. The fuel nozzle is metallurgically integrally jointed to a base plate supporting the fuel nozzle. A boundary surface between the fuel nozzle and the base plate is joined by fusion-welding or brazing at their surfaces and the inside thereof is joined by pressure-welding.SELECTED DRAWING: Figure 1 【課題】耐久性及び強度信頼性に優れたガスタービン燃焼器の燃料ノズルを提供する。【解決手段】ガスタービン燃焼器の燃焼室に燃料を噴出するガスタービン燃焼器の燃料ノズルであって、前記燃料ノズルは、当該燃料ノズルを支持するベースプレートと冶金的に一体化接合されており、前記燃料ノズルと前記ベースプレートの界面は、表面において融接またはロウ付けにより接合され、内部は圧接により接合されていることを特徴とする。【選択図】 図１
