Abstract
An actuator included in a head substrate of an ink-jet head receives, with an electrode on the surface of the actuator, power fed from the wiring of a wiring substrate arranged opposite the head substrate. A first electrode of the wiring substrate is electrically connected to the wiring, and protrudes to the side of the head substrate. A second electrode is electrically connected to the electrode on the surface of the actuator, protrudes to the side of the wiring substrate and is electrically connected to the first electrode. The head substrate and the wiring substrate are adhered to each other through an adhesive layer such that a space to which the first electrode and the second electrode are exposed is hermetically sealed. The hermetically sealed space is in a vacuum state or is filled with a gas containing a predetermined amount of water or less.
