Abstract:
1. An ink-jet head comprising: a wiring substrate having a wiring; and a head substrate including wherein the wiring substrate includes a first electrode that is electrically connected to the wiring and that protrudes to a side of the head substrate, wherein the actuator includes a second electrode that is electrically connected to the electrode, that protrudes to a side of the wiring substrate and that is electrically connected to the first electrode, wherein 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, wherein the hermetically sealed space is in a vacuum state or is filled with a gas containing a predetermined amount of water or less, wherein the adhesive layer is formed with a thermosetting adhesive resin layer, and wherein a melting point of one of the first electrode and the second electrode is equal to or less than a curing temperature when the head substrate and the wiring substrate are joined together with the thermosetting adhesive resin layer.
