PROBLEM TO BE SOLVED: To provide a burner device capable of maintaining flame stability well at a combustion plate even if the flow velocity distribution of combustion air is uneven in high-load combustion. SOLUTION: This burner device comprises a mixing part 20 for mixing fuel gas and combustion air; the combustion plate 16 having a plurality of burner ports 18; a fuel gas supply means 24 for supplying fuel gas to a mixing part 20; and a combustion air supply means 50 for supplying combustion air to the mixing part 20. The mixing part 20 is composed of a plurality of mixing units 28, and each mixing unit 28 has first and second mixing passages 30, 32 extending toward the combustion plate 16, and a fuel injection nozzle 42 disposed in the first mixing passage 30. The first and second mixing passages 30, 32 are partitioned by partition walls 38, 40, and the partition walls 38, 40 are provided with gas supply holes 46 corresponding to gas jet ports 44 of the fuel injection nozzle 42.
