A combustor comprising: a plurality of nozzles which is arranged around the central axis of the combustor and of which each base end is connected to an oil supply tube; a nozzle tube base (20, 50, 50A) which supports the plurality of nozzles and includes an oil chamber for supplying fuel to the nozzles via an oil inflow portion provided in each oil supply tube; a first guide portion which faces the center of the combustor inside the oil chamber and is arranged to guide the oil remaining inside the oil chamber to the oil inflow portion; and a second guide portion which faces the base end of the combustor inside the oil chamber and is arranged to guide the oil remaining inside the oil chamber to the oil inflow portion, wherein the first guide portion, located between two adjacent oil inflow portions, includes a first inclination surface that is inclined in a direction away from the center of the combustor as it becomes closer to one oil inflow portion and a second inclination surface that is inclined in a direction away from the center of the combustor as it becomes closer to the other oil inflow portion, and the second guide portion includes a third surface that is located closer to the vicinity of the front end of the combustor than the oil inflow portion, characterized in that the third surface is an inclination surface that is inclined in a direction away from the central axis of the combustor as it becomes closer to the oil inflow portion, the oil inflow portion includes a base end opening which is formed in the oil supply tube and is opened toward the base end of the combustor, and the oil inflow portion includes a perforation hole which is formed in a tube wall of the oil supply tube. a plurality of nozzles which is arranged around the central axis of the combustor and of which each base end is connected to an oil supply tube; a nozzle tube base (20, 50, 50A) which supports the plurality of nozzles and includes an oil chamber for supplying fuel to the nozzles via an oil inflow portion provided in each oil supply tube; a first guide portion which faces the center of the combustor inside the oil chamber and is arranged to guide the oil remaining inside the oil chamber to the oil inflow portion; and a second guide portion which faces the base end of the combustor inside the oil chamber and is arranged to guide the oil remaining inside the oil chamber to the oil inflow portion, wherein the first guide portion, located between two adjacent oil inflow portions, includes a first inclination surface that is inclined in a direction away from the center of the combustor as it becomes closer to one oil inflow portion and a second inclination surface that is inclined in a direction away from the center of the combustor as it becomes closer to the other oil inflow portion, and the second guide portion includes a third surface that is located closer to the vicinity of the front end of the combustor than the oil inflow portion, characterized in that the third surface is an inclination surface that is inclined in a direction away from the central axis of the combustor as it becomes closer to the oil inflow portion, the oil inflow portion includes a base end opening which is formed in the oil supply tube and is opened toward the base end of the combustor, and the oil inflow portion includes a perforation hole which is formed in a tube wall of the oil supply tube.
