PCT No. PCT/JP97/00462 Sec. 371 Date Oct. 20, 1997 Sec. 102(e) Date Oct. 20, 1997 PCT Filed Feb. 20, 1997 PCT Pub. No. WO97/30793 PCT Pub. Date Aug. 28, 1997A liquid coating nozzle is provided with a first block which has an inner liquid reserving section that extends in the longitudinal direction and an inner discharge section which includes a plurality of small holes formed in the longitudinal direction at a bottom portion of the liquid reserving section. The nozzle is also provided with a second block which has an inner space defining a gas reserving section that extends in the longitudinal direction outside the first block and an outer discharge section formed in the longitudinal direction at a bottom portion of the inner space. The outer discharge section includes a plurality of small holes and produces a gas flow that externally surrounds a linear or curtain-shaped liquid flow that flows downward from the small holes. This results in the formation of a thin coating film in a short time and reduces the consumption of liquid and coating nonuniformities.
