Zusammenfassung:	PROBLEM TO BE SOLVED: To realize high efficiency in a wide combustion load range from rated combustion to a low combustion load, in a burner device which supplies and burns fuel gas G to a flow passage A1 for main combustion and a flow passage A2 for pilot combustion.SOLUTION: A plurality of first supply ports 5 for supplying fuel gas G into a flow passage A1 for main combustion are dispersely arranged in the direction separating from the side of a flow passage A2 for pilot combustion of the flow passage A1 for main combustion. Ejection resistance of fuel gas G caused by the distribution of oxygen-containing gas A at each first supply port 5 is set to be increased as being separated from the side of the flow passage A2 for pilot combustion.
