摘要: A laser processing apparatus includes: a scan moving unit which moves one or both of a workpiece and a laser beam; a laser beam irradiation unit which irradiates the workpiece with the laser beam; and a gas discharge unit which discharges at least a first gas to an irradiation area irradiated with the laser beam in the workpiece. The gas discharge unit has a rectifying surface at a position facing the workpiece during laser beam irradiation. The rectifying surface is provided with a first gas discharge port through which the first gas is discharged; and one or both of a second gas discharge port and a gas front-back suction port. The second gas discharge port discharges a second gas to the workpiece during laser beam irradiation on both outer sides of the first gas discharge port at least in the scanning direction.
