ABSTRACT:
A liquid transport apparatus constructed by stacking a plurality of plates includes a flow passage unit having pressure chambers, a common liquid chamber, and communication flow passages communicating the pressure chambers and the common liquid chamber, and a pressure-applying mechanism which applies a pressure to the liquid in the pressure chambers. The plurality of plates include a first plate and a second plate joined to a surface of the first plate. A recess, which has an opening at the surface and which constructs the common liquid chamber, is formed for the first plate. A projection extends from the bottom wall of the recess to make contact with the second plate. Therefore, when the plurality of plates are stacked and joined to one another, it is possible to sufficiently apply a pressure to the portion overlapped with the common liquid chamber, and the plates make tight contact with each other.
