PROBLEM TO BE SOLVED: To perform the laser beam machining of an object to be machined (hereinafter called as a workpiece) even when a part of the workpiece is chipped. SOLUTION: A laser beam machining apparatus includes a laser beam source for emitting laser beam, a holding stand for holding the workpiece, an optical system causing the laser beam emitted from the laser beam source to be incident on the workpiece held on the holding stand, an imaging apparatus for imaging an image of the workpiece held on the holding stand, and a control device which determines the scanning range of the laser beam on the workpiece based on the profile of the workpiece with its image being imaged by the imaging apparatus so as not to reach a chipped portion if the workpiece has any chipped portion, and which controls the operation of at least one of the optical system and the holding stand so that the laser beam is incident on the scanning range.
