Liquid jetting head, method of manufacturing the same, and liquid jetting apparatus incorporating the same

摘要

A first substrate defines a plurality of pressure generating chambers. The first substrate includes a vibration plate which forms a first surface of the first substrate, and formed with a first through hole. A plurality of piezoelectric elements are provided on the vibration plate. A second substrate is bonded onto at least the first surface of the first substrate. The second substrate is formed with a second through hole communicated with the first through hole. A laminated film includes a coating layer comprised of a resin material. The laminated film is provided on an inner wall face of a communicating portion at which the first through hole and the second through hole are connected.
