The laser processing device (100) includes a laser irradiation unit (1) that performs processing on a workpiece (W) by using a laser while scanning a workpiece surface to form a kerf, jet nozzles (3) that respectively form jet flows (Fj) flowing toward a bottom surface of the kerf on front and rear sides in a scanning direction of the laser (1), and an intake part (23) that sucks, above injection ports of the jet nozzles (3) , a gas in a region surrounded by the jet flows (Fj) from the front and rear sides. In a state in which a certain region of the kerf is isolated by the jet flows (Fj), the gas is sucked from this region by the intake part (23). As a result, a suction force by the intake part (23) can reach the bottom surface of the kerf.
