Abstract: Disclosed is a processing nozzle for simultaneously ejecting a plurality of types of powder materials. This processing nozzle is a processing nozzle used to eject a powder material to a molten pool formed on a process surface by a laser beam, and includes an inner housing that forms an optical path to pass the laser beam, and an outer housing arranged while being separated from the inner housing by a gap serving as a first supply path of the powder material. A second supply path of the powder material and a third supply path having a diameter different from the second supply path are provided inside the outer housing.
