    • A laser processing method in which the sectional shape at a focusing point P of a laser beam L is such that a maximum length in a direction perpendicular to a scheduled cutting line (5) is shorter than a maximum length in a direction parallel to the scheduled cutting line (5). Therefore, the shape of a modified region (7) formed inside a silicon wafer (11), when viewed from a laser beam L incident direction, is such that a maximum length in a direction perpendicular to a scheduled cutting line (5) is shorter than a maximum length in a direction parallel to the scheduled cutting line (5). When the modified region (7) having such a shape is formed inside an object (1) to be processed, twist hackle can be prevented from appearing on a cut section when the object (1) to be processed is cut with the modified region (7) as a cutting start point, whereby it is possible to improve the flatness of a cut section.
