PROBLEM TO BE SOLVED: To provide a gas-liquid spray nozzle of slit type that is easy to be machined and is fabricated at low cost, and can perform a uniform spray at very close range. SOLUTION: Two slits are formed longitudinally between three planks 11, 12, 13, and one of them is used as a jet nozzle 17 for gas, while another slit is used as a jet nozzle 16 for liquid. The tip of the central plank 12 is protruded ahead of the jet nozzle 17, forming a slope 18 toward another jet nozzle 16. The gas deflects along the slope 18 due to its viscosity and collides with the liquid. A similar slope may be formed on the back of the slope 18 and also both outside planks 11 and 13 may be extended forward to serve as guides for spray liquid.
