The present invention provides a laser cutting device which is capable of carrying out cutting without reducing the quality of the cutting surface, when laser cutting is carried out on a laminated body. In the laser cutting device, a chamber (5) is configured between a lens (4) and the laminated body (10). A transmission window (6) through which laser (2) is irradiated in the chamber (5), an air feeding in port (7) for leading auxiliary gas (8) into the chamber (5), and a notch (9) for enabling the laser (2) to emit from the chamber (5) and to allow the auxiliary gas (8) to spray out from the chamber (5). The notch (9) is provided with a shape which is similar to the resign in which laser scanning is carried out. The thickness, at the irradiation position of the laser (2), of the laminated body (10) reduces when the auxiliary gas (8) is sprayed. |
