Abstract
An element-group formation substrate () having plural semiconductor light emitting elements () formed on a substrate front surface () is sequentially irradiated with a laser beam () having a first output from a substrate back surface () side in the y direction, and the laser beam () is sequentially collected to a part having a first depth Dfrom the substrate back surface (), thereby forming a first modified region L. The substrate () having the first modified region Lformed therein is sequentially irradiated with the laser beam () having a third output (<the first output) from the substrate back surfaceside in the y direction, and the laser beam () is sequentially collected to a part having a third depth Dfrom the substrate back surface () shallower than the first depth D, thereby forming a third modified region L
