PROBLEM TO BE SOLVED: To provide a fuel nozzle wherein mixing action of a liquid fuel and air is improved. SOLUTION: The liquid fuel nozzle is provided. The fuel nozzle comprises a rod-shaped body, a cylindrical premixing nozzle disposed substantially in a concentric fashion with respect to a central axis of the rod-shaped body, and in the rod-shaped body a liquid fuel flow passage, a plurality of liquid fuel injection holes formed substantially at an equal interval peripherally in the neighborhood of an end of the rod-shaped body and communicated in an inclined state with respect to the liquid fuel flow passage, and a partition ring disposed concentrically to the central axis between the cylindrical premixing nozzle and the rod-shaped body. The partition ring has holes at positions corresponding to parts of the plurality of the liquid fuel injection holes, whereby a liquid fuel injected from part of the liquid fuel injection holes among the plurality of the liquid fuel injection holes is injected so as to pass through the holes and collide against an internal surface of the cylindrical premixing nozzle, and the liquid fuel injected from the remaining liquid fuel injection holes among the plurality of the liquid fuel is injected in the direction of colliding against the internal surface of the partition ring.
