Abstract
A laser processing method includes forming a first processing mark to form an origin of dividing or a dividing groove with a laser beam in a first direction, and forming a second processing mark by forming an origin of dividing or a dividing groove with the laser beam in a second direction that intersects the first direction. An unprocessed region in which the processing is not executed remains at an intersection at which the first direction and the second direction intersect each other. The method further includes processing the unprocessed region. The unprocessed region processing step forms a coupling processing mark that couples the first processing mark and the second processing mark to each other to form an origin of dividing or a dividing groove with the laser beam in a direction arising from setting an inclination with respect to the first direction or the second direction.
