Abstract: A method is disclosed for dividing a composite material in which a brittle material layer and a resin layer are laminated, including: irradiating the resin layer with a laser beam L1 oscillated from a CO2 laser source along scheduled dividing lines DL of the composite material to form a processing groove along the scheduled dividing lines; and irradiating the brittle material layer with a laser beam L2 oscillated from an ultrashort pulsed laser source along the scheduled dividing lines to form a processing mark along the scheduled dividing lines. In the resin removing step, in a region IS where the scheduled dividing lines intersect, the laser beam oscillated from the CO2 laser source is not irradiated multiple times, or an irradiation amount of the laser beam is decreased relative to an irradiation amount in a region other than a region where the scheduled dividing lines intersect.
