ABSTRACT:
A liquid transfer device of the present invention includes a passage unit, an energy supplier, and a supporter. In the passage unit, a common liquid chamber and a plurality of individual passages branching off from the common liquid chamber are formed. Such a passage unit includes a plurality of plates which are laminated on one another and include a first plate having a hole constituting the common liquid chamber and a second plate. The energy supplier supplies, to liquid in the individual passages, energy for transferring the liquid. The supporter projects inwardly from a side wall defining the hole formed on the first plate, and is continuous from one end to the other end of the common liquid chamber in a laminating direction of the plates so as to support the second plate in the laminating direction.
