Abstract
A laser processing method includes a laser processing step of converging laser light to an object including a first surface and a second surface opposite to the first surface using the first surface as an incident surface to form a converging spot of the laser light, while relatively moving the converging spot with respect to the object, thereby performing laser processing in the object, the object being provided with a grinding planned area along the incident surface, and the laser processing step including a first forming step of relatively moving, while setting a position of the converging spot in a Z direction intersecting with the incident surface at a first Z position, the converging spot along a line extended in an X direction along the incident surface, thereby forming a first modified region and a first fracture extended from the first modified region in the object.
