Summary:PROBLEM TO BE SOLVED: To provide a laser beam machining method by which the surface of an object to be machined can be machined even when the surface shape of the object to be machined is complicated. SOLUTION: Laser beams L are emitted from the upper part and the lower part when three coaxial cables 1 are arranged on the same plane in parallel as the object to be machined. Simultaneously, assist gas is supplied from the underside of the object to be machined and sucked on the upside. Thereupon, because the density of the assist gas is raised in the gap part between adjacent coaxial cables 1 where the light quantity of the laser beam which is made incident per unit area is little and the machining speed of the laser beams is apt to be lowered, sufficient laser beam machining is performed without generating unprocessed parts by the accelerating effect of the laser beam machining caused by the assist gas.
