description	PROBLEM TO BE SOLVED: To improve a two fluid nozzle for externally mixing a liquid with a gas. SOLUTION: The two fluid nozzle is provided with a double cylinder comprising an outer cylinder and an inner cylinder having the same center axis line to form the hollow part of the inner cylinder into a liquid flow passage and a space between the inner cylinder and the outer cylinder into a gas flow passage. The gas flow passage is provided with: a jetting side gas flow passage held between a first tapered surface provided to be tilted to the center axis line on the jetting side inner surface of the outer cylinder and a second tapered surface provided to be tilted to the center axis line on the outer surface of the inner cylinder and having cross section increased toward a jetting port; an orifice flow passage provided right before reaching the jetting side gas flow passage, held between the inner surface of the outer cylinder and the outer surface of the inner cylinder to be parallel to the center axis line and having the cross-section smaller than the cross-section of the jetting side gas flow passage; and a turning flow passage provided to the gas flow passage of the upstream side of the orifice flow passage to form a turning flow by a turning means.
