摘要

The liquid coating nozzles 4, 4a and 124 have an inner discharge portion including an inner liquid storage portion 43 extending in the longitudinal direction and a plurality of small holes 44 formed in the longitudinal direction at the bottom of the liquid storage portion 43. The branch is formed in the longitudinal direction at the bottom of the inner space and the inner space forming the first block 41 and the gas storage portion 46 extending in the longitudinal direction from the outside of the first block 41 and also a plurality of small holes. A second block 42 composed of 48 and having an outer discharge portion for forming a gas flow that surrounds the linear or curtain liquid flow flowing downwardly from the small hole 44 is provided so as to generate non-uniformity of the coating. It is possible to form a thin coating film in a short time while suppressing the consumption of excessive liquids.
