摘要： An object is to improve the quality of a processed composite material without reducing the processing rate. A processing apparatus includes a laser head configured to irradiate a front face of a composite material with a laser beam and a gas supply unit configured to supply an assist gas to an irradiation point irradiated with the laser beam by the laser head. The gas supply unit has a first-level nozzle configured to eject the assist gas to an area at or near the irradiation point and a second nozzle configured to eject the assist gas to an area at or near the irradiation point and arranged above the first-level nozzle. The angle of the direction in which the first-level nozzle ejects the assist gas relative to the front face differs from the angle of the direction in which the second nozzle ejects the assist gas relative to the front face.
