摘要： The present invention provides a laser processing method which improves strength and quality of an object to be processed after working. In the present embodiment, after modified regions 7 are formed along the outlines of hollowed-out portions Q1 and Q2 in the object 1 by irradiating the object 1 with a laser light, etching is performed onto the object 1 to selectively advance etching along a fracture which is contained in the modified regions 7 or extend from the modified regions 7, and the hollowed-out portions Q1 and Q2 are spaced and moved from the object 1. Here, the modified regions 7 are formed so as to connect to each other along the outlines of the hollowed-out portions Q1 and Q2, and further exposed on a surface 3 side of the object 1. In this way, in the present embodiment, it is possible to perform working so as to hollow out the hollowed-out portions Q1 and Q2 from the object 1 without applying external stress, and it is possible to remove the fracture generated according to the formation of the modified regions 7 by etching.
