PROBLEM TO BE SOLVED: To provide a burner apparatus capable of providing favorable combustion by providing very easy accurate attachment work of a gas ejection nozzle facing an inlet. SOLUTION: A connection plate 19 is integrally provided on an inlet body 6 provided with the inlet 4 and a throat part 5. The connection plate 19 is connected to a nozzle holder 20 by screwing, and the gas ejection nozzle 12 is faced toward the inlet 4. An extension piece 24 facing the inlet 4 is integrally provided on the connection plate 19. A positioning hole 25 concentric with the throat part 5 and adhered to an outer side of the gas ejection nozzle 12 is provided on the extension piece 24. The gas ejection nozzle 12 is positioned by inserted it into the positioning hole 25, and the nozzle holder 20 is connected to the connection plate 19 by screwing. Just by inserting the gas ejection nozzle 12 in the positioning hole 25, the nozzle holder 20 is positioned in a connection position of a connection plate 16, oblique fastening of a screw 21 is prevented, and the nozzle holder 20 can be easily and accurately connected to the connection plate 19 by screwing.
