Abstract
A first laser beam (2) and a second laser beam (3) composed of an ultraviolet laser are irradiated from a side of a second glass member (5b), allowing the first laser beam (2) to pass through the second glass member (5b) so as to condense the first laser beam (2) on the first glass member (5a) to form a first scribe line (14), condensing the second laser beam (3) on the second glass member (5b) to form a second scribe line (15), and applying a break force to the first scribe line (14) and the second scribe line (15) to cut the glass.
