PROBLEM TO BE SOLVED: To provide a gas burner superior in heat efficiency, and indicating a low NOx value in a state of the small air mixing ratio. SOLUTION: The purpose is attained by forming a burner having a part 17 for mixing a part (primary gas) of fuel gas and air, a dividing plate 20 for blowing out the mixed fuel gas and air by being divided into a plurality, and a mechanism for blowing out a residual part (secondary gas) of the fuel gas to the combustion side of the dividing plate 20. This gas burner is desirably in a range of the primary gas:the secondary gas = (50:50 to 97:3) in the volume ratio on the distribution ratio of the primary gas and the secondary gas. A nozzle port of the secondary gas may be singular or plural. A blowout position can be changed. COPYRIGHT: (C)2003,JPO
