Patent ID: 7438395

Claim:
A liquid-jetting apparatus comprising: a plurality of liquid flow passages which include a plurality of nozzles configured to jet a liquid and a plurality of pressure chambers communicating with the plurality of nozzles respectively; an actuator configured to selectively change volumes of the plurality of pressure chambers, wherein: the liquid flow passages are formed by a plurality of stacked plates, the actuator is arranged between a pressure chamber plate which is included in the plurality of plates and which forms the plurality of pressure chambers and a nozzle plate which has an insulating property at least on a surface opposed to the pressure chamber plate and which is formed with the nozzles, and the actuator includes a vibration plate which defines a portion of each of the plurality of pressure chambers, a piezoelectric layer which is provided on a surface of the vibration plate disposed on a side not facing the plurality of pressure chambers, and a plurality of individual electrodes which are formed at positions opposed to the plurality of pressure chambers respectively on a surface of the piezoelectric layer disposed on a side not facing the vibration plate; and a plurality of wiring sections, which are connected to the plurality of individual electrodes respectively, are formed on the surface of the nozzle plate and disposed on a side of the actuator; wherein the nozzle plate and the piezoelectric layer are adhered to one another by an anisotropic conductive material which has conductivity in a compressed state.
