A laser processing device for preventing the deterioration of a digital micromirror device or the optical fiber is provided to perform the laser processing by simply easily changing the intensity of the beam to be irradiated to a processing object. A laser processing device(1) comprises: a laser source(3) generating the beam to be irradiated to a processing object(A); a digital micromirror device(4) irradiating the beam to the processing object to the specific location with a specific form; and a irradiation optical system(5) irradiating the beam configured with the spatial modulation element.
