PROBLEM TO BE SOLVED: To provide a slit nozzle for two fluids in which a range capable of setting a spray pressure of a slit nozzle is broadened and an improper spraying is not caused. SOLUTION: There is provided a slit nozzle for two fluids in which an injection hole in a slit shape 23 is provided along an end surface in the lengthwise direction of an oblong body, a liquid flow path 20 and a gas flow path 16 are provided along the lengthwise direction of the oblong body therein, and a gas-liquid impingement mixture portion 21 is provided by merging the liquid flow path 20 with the gas flow path 16 at a crossing angle (θ2) of 45°to 90°on the side of the injection hole in a slit shape 23, wherein the gas-liquid impingement mixture portion 21 and the injection hole in a slit shape 23 are communicated through a flow path with a small diameter 22, and the injection hole in a slit shape 23 is set so as to have a slit width lower than a width of the flow path with a small diameter 22.
