The second substrate is joined to the second surface of the first substrate and has a channel communicating with the pressure chamber via the communication hole. The pressure chamber has a first end in a first direction and a center portion in the first direction. The communication hole communicates with the first end of the pressure chamber, and the first end of the pressure chamber is greater than the center portion of the pressure chamber in length in a second direction which intersects with the first direction.
