The mixing chamber includes a first mixing chamberbroadening toward a downstream side. The memberincludes air introduction holesformed in a plurality of rows in an axial direction, with the air introduction holes being arranged plurally in a circumferential direction of the mixing chamber. The memberincludes a fuel ejection holeprovided in a wall surface which forms the air introduction hole. The air introduction holesare circumferentially eccentrically installed. The air introduction holeslocated in the most upstream row are more inclined toward the downstream side than the air introduction holeslocated in the rows other than the most upstream row.
