Abstract (en)
[origin: EP3603978A1] A first inflow port (20) allows a first liquid (31) to flow into a liquid flow passage (13), and a second inflow port (21) allows a second liquid (32) to flow into the liquid flow passage (13). The first and second liquids (31, 32) flow toward a pressure chamber (18). There is a portion satisfying L ≥ W, where L is a length of the first inflow port (20) and W is a length of the liquid flow passage (13) above the first inflow port (20), in a direction orthogonal to a direction of flow of the first liquid (31) in the pressure chamber (18) and to a direction of ejection of the second liquid (32) from an ejection port (11). In a case where the second liquid (32) is ejected from bottom to top, the second liquid (32) flows above the first liquid (31).
