Abstract
A tip section of a discharge nozzleis shaped like a wedge, and projectionswhich further protrude are formed at the tip of the wedge. Lower surfacesof the projectionsdefine a substrate-facing-surface which is brought into proximity to the substrate, and discharge outlet bearing surfaceswhich gradually retract back from the substrate W, are formed as if to rise from the edges of the lower surfacesAt adjacent positions within the discharge outlet bearing surfacewhich are adjacent to the substrate-facing-surface, discharge outletsfor discharging an application liquid are opened. Areas around the discharge outletsand a wall around a fluid feeding pathare integrated with each other.
