Abstract: A laser machining apparatus includes an irradiating section and a control section. The control section causes, in a first period, the irradiating section to perform a first cutting process for cutting a workpiece in a region between a first region and a second region in such a manner that a state in which the first region is retained by the second region in the workpiece is kept, and causes, in a second period later than the first period, the irradiating section to perform a second cutting process for cutting the workpiece within the region between the first region and the second region in the workpiece, where a rear surface is exposed because a part of the protective sheet has been melted in the first cutting process, to separate the first region from the second region together with dross adhering to the rear surface in the first cutting process.
