A laser machining apparatus (100) for machining a workpiece (W) placed and fixed on a table (108) by moving the irradiation position of a laser beam on the workpiece while irradiating the workpiece is provided with: a laser oscillator (156); a laser irradiation head (110) that emits the laser beam from the laser oscillator toward the workpiece and that is provided with a galvano-scanner for moving a laser beam irradiation position on the surface of the workpiece in two directions; a parallel manipulator (130) that changes the orientation of the laser irradiation head; a slide member (114) that supports the parallel manipulator; and linear feed shaft device (150, 152) that moves the slide member in at least two orthogonal directions relatively to the table.
