PROBLEM TO BE SOLVED: To provide a laser processing device in which dust of debris etc. generated by irradiating a workpiece with a laser beam from a condenser can be exhausted without impeding the optical path of the laser beam irradiated from the condenser.SOLUTION: Dust exhausting means comprises a dust suction unit 71 arranged below a condenser 51 and suction means 72 connected to the dust suction unit. The dust suction unit is formed as U-shaped by a rectangular top wall 711 which comprises an opening 711a for allowing passing of a laser beam irradiated from the condenser and a first side wall and a second side wall each of which descends vertically from both side edges of the top wall respectively. The suction means 72 comprises a suction duct 721, one end of which is connected to one side of rectangular openings formed at both ends of the top wall 711, the first side wall and the second side wall in the dust suction unit 71 respectively and the other end of which is connected to a suction source. |
