Inkjet head and methods of manufacturing the inkjet head

Abstract

An inkjet head comprises a pressure chamber, piezoelectric elements, and pressure chamber electrodes disposed on an interior side of the pressure chamber, the pressure chamber electrodes being configured to apply a driving voltage to the piezoelectric elements. The inkjet head also includes a nozzle plate adhered to the frame body with the resin film. The nozzle plate includes an ink discharge hole configured to discharge ink. The inkjet head includes a frame body including an attaching part to which a mask that surrounds the outer perimeter of the inkjet head is to be attached. The inkjet head also includes a resin film that coats the pressure chamber electrodes and that includes an end portion that extends to and covers the attaching part. The inkjet head also includes a layer that coats the end portion of the resin film and by which the mask is to be adhered to the frame.
