Claim Text:
1. A liquid jetting apparatus configured to discharge a liquid, comprising: a channel structure in which a liquid channel, including a nozzle and a pressure chamber communicating with the nozzle, is formed; a piezoelectric element including: a driving device electrically connected to the electrode to drive the piezoelectric element; and a cover member joined to the surface of the channel structure so that the cover member is stacked on the surface to cover the piezoelectric element; wherein a first wiring section connected to the electrode is formed on the surface of the channel structure; wherein the cover member includes: wherein a second wiring section is formed in the cover member, the second wiring section being connected to the driving device and extending from the cover body section to a surface, of the wiring connection section, facing the first wiring section; wherein the wiring connection section is joined to the surface of the channel structure in a state that the second wiring section is electrically conductive with the first wiring section; wherein a thickness, of the wiring connection section, in a direction of stacking of the channel structure and the cover member is thinner than a thickness, of the cover body section, in the direction of stacking of the channel structure and the cover member; and wherein the cover body section and the wiring connection section comprise electrically insulating material.
