PROBLEM TO BE SOLVED: To provide a coating nozzle apparatus with a simple structure, light in weight, and whose slit gap is easily adjustable. SOLUTION: This coating nozzle apparatus 10 is composed of a nozzle main body 20, a lower blade member 30 working also as a cover, and an upper blade member 40 and the nozzle main body 20 is subjected to precise plane processing to attach the lower blade member 30 and the upper blade member 40 in so-called metal touch manner and to tnake a gasket no need. Since no gasket is required and the number of the constituent members is lessened, the coating nozzle apparatus 10 can be miniaturized and made light in weight. Additionally, a coating material is passed zigzag through a nozzle hole 27, a slit path 35, a slit nozzle 44 in this order. Consequently, while the slit length enough to obtain excellent film-like flow being kept, the length of the slit nozzle 44 to be kept in a cantilever state can be shortened. Also owing to that, the coating nozzle apparatus 10 can be miniaturized and made light in weight.
