Abstract (en)

In a nozzle block (60), a first space (64), a second space (66), and a third space (67) are aligned from a first side toward a second side in a predetermined direction. The second space (66) is spread at a second inner surface tapered angle from the first side toward the second side. The third space (67) is spread at a third inner surface tapered angle greater than the second inner surface tapered angle from the first side toward the second side. A height (H1) of the first space (64) is a value greater than or equal to 3 mm and smaller than or equal to 8 mm. A height (H2) of the second space (66) is a value greater than or equal to 30% and smaller than or equal to 50% of a sum of the height (H2) and a height (H3) of the third space (67).
