Ink jet head, connecting sheet, composite sheet, and method of manufacturing ink jet head and composite sheet

摘要

An ink jet head is provided with a main body, a wired sheet, and a connecting sheet. The main body is provided with a plurality of sets and each set includes an input terminal, an actuator, a pressure chamber and a nozzle. The wired sheet is provided with a plurality of sets and each set includes a signal line and an output terminal. The connecting sheet is provided with an insulating sheet and a plurality of sets and each set includes first terminal formed on a first face of the insulating sheet and a second terminal formed on a second face of the insulating sheet. In each set, the signal line, output terminal, second terminal, first terminal, input terminal and actuator are electrically connected. When a voltage is applied to the actuator in a selected set via the signal line, output terminal, second terminal, first terminal and input terminal, pressure is applied to ink within the pressure chamber in the selected set, and this ink jets from the nozzle in the selected set.
