A laser machining apparatus capable of removing spatters and slugs produced in piercing and rising supply pressure of blow gas sufficiently without hindering a jet of assist gas. A piercing assist jig can be turned and moved up and down by a rotary air cylinder and an extendable air cylinder which are attached to a machining head. When piercing is to be performed, the piercing assist jig, which is in a position where it does not interfere with the machining nozzle and the workpiece, is turned to make a center of a hole of the piercing assist jig coincide with a center of the machining nozzle. Then the machining head is moved down to a piercing position, and the piercing assist jig is pressed on a workpiece. Then, a laser beam is irradiated and assist gas is jetted, and also blow gas is jetted from a blow gas supply opening so that the blow gas flows with the assist gas therebetween. Spatters and slugs flying up in the process of piercing are removed by the blow gas without hindering the piercing.
