PROBLEM TO BE SOLVED: To provide a two-fluid slit nozzle for spraying by providing with a mixing space in which two fluids collide at right angles each other in a slit nozzle in order to obtain a film-like spray mist homogeneous in the longitudinal direction by mixing a liquid with a gas, and passing through a means for further homogenizing the mixture fluid. SOLUTION: A mixing plate is inserted to be held between a long platy liquid feeding plate and a gas feeding plate. A liquid which is fed through a liquid orifice penetrated through a mixing plate from the liquid feeding plate is collided to mix with air in a mixing space on another face of the mixing plate, the air being fed through an air orifice from one air feeding plate to the other face of the mixing plate. The film of spray mist is sprayed from a spray slit by communicating the downstream end of the mixing space and the upstream end of the spray slit between the lower end faces of both of the mixing and air feeding plates by a colliding chamber for conducting homogenization and acceleration by expanding and compressing formed by connecting two groups of orifices penetrating through the mixing plate at the side of the liquid feeding plate between the two groups of orifices.
