Abstract
While a converging lensis relatively moved along a lineincluding a line to cut, measuring laser light Lis converged with the lenswhen the lensis positioned on a processing regionhaving an outer shape between an object to be processedand a frame, and a reflected light component of the laser light Lreflected by a front faceof the objectis detected. While keeping a substantially constant distance between the front faceand the lenssuch that a converging point P of processing laser light Lis positioned at a constant distance from the front faceaccording to the detection, the laser light Lis converged by the lens, so as to form a molten processed regionwithin the object
