PROBLEM TO BE SOLVED: To generate high-temperature flame and easily accurately adjust the flame temperature, the flame thickness, the flame length and others in conformation to a burner work. SOLUTION: This gas burner is adapted to supply fuel and air to a plurality of nozzles 12 and 13 arranged on the same concentric circle through the same fuel supply system 210 and air supply system 220, and supply fuel and air to central nozzles 11 through a fuel supply system and an air supply system for nozzle in the center. A variable flow adjusting device 22 is interposed in the fuel supply system 210, a flow adjusting device 23 for setting an air flow rate is interposed in the air supply system 220, and the fuel supply system and the air supply system are combined together in a position closer to the nozzles from the flow adjusting device 23 of the air supply system 220 and closer to the nozzles from the variable flow adjusting device 22 of the fuel supply system.
