Abstract
In a laser cutting method, a cut slit of a welding protruding-tab configured to be bent by laser cutting along an outline of a processed part and press a peripheral surface of the processed part is laser-cut in advance in a periphery of the processed part that is cut from a workpiece, and an outline slit is formed by performing laser cutting along the outline of the processed part and a free end of the welding protruding-tab is welded to the peripheral surface of the processed part. According to the above described laser cutting method, it is possible to retain the processed part reliably and stably for a long period, and it is possible to easily separate the processed part from the workpiece with almost no trace left on the processed part.
