To provide a laser beam machining head by making a condensing laser beam and a plasma arc coaxial so as to make a laser beam a wide heat source by reinforcement of a plasma arc and to effect efficient machining in high precision.
To a tip part 6 of the laser beam machining head 10, which is arranged with optical systems 4, 5 to condense a laser beam oscillated from a laser beam oscillator 1, a plasma machining head 20 is arranged coaxial to the optical system 4, 5. The plasma machining head 20, is arranged with an electrode nozzle 24, etc., to be connected to a plasma device 15 and a working gas supply passage 19 to be connected to the electrode nozzle 24, etc., a same position 14 to be machined of a work 13 is irradiated both with the laser beam 11 and the plasma arc 28.
