PROBLEM TO BE SOLVED: To provide a burner apparatus capable of positively mixing fuel gas and primary air without obstructing flowing in a mixing pipe part interior, and capable of providing favorable combustion by comparatively enlarging a bore of a suction opening and a flowing cross-sectional area of a throat part. SOLUTION: A stream lining member 22 is provided on an outer side of the suction opening 4 facing a gas jetting nozzle 12 and sucking in the fuel gas and the primary air. A flow dividing plate 23 extending in a direction intersecting one part of the suction opening 4 at a position above the gas jetting nozzle 12 and separated from the suction opening 4, is provided on the stream lining member 22. In the flow dividing plate 23, one part of the primary air heading for the suction opening 4 is divided by abutment, and by disturbing a flow of the primary air, the fuel gas and the primary air are favorably mixed in the throat part 5 and the mixing pipe part 7.
