PROBLEM TO BE SOLVED: To provide a slit nozzle capable of reducing idle time for bubble removal work and removing striped unevenness of a coating film caused by bubbles. SOLUTION: Bubbles (air) entrained in a coating solution are stagnated in the ceiling part of a first storage part 4 after getting off the coating solution during the time the coating solution flows from the first storage part 4 to a second storage part 5 and since the first storage part 4 is formed just like a range of two mountains, the air reaches the top part along the ceiling and is discharged out of a bubble discharge port 7 opened there.
