Abstract: A liquid jet head includes a piezoeletric body substrate and an opaque substrate bonded to the piezoelectric body substrate. The piezoeletric body substrate has ejection grooves arrayed with an identical pitch P in a reference direction and non-ejection grooves arrayed alternately with the ejection grooves while shifted from the ejection grooves by a half pitch (P/2). The opaque substrate has through holes arrayed in the reference direction. The through holes include a row of through holes corresponding in number to and communicating with the respective ejection grooves, a first through hole arranged outside of one end side of the row of through holes so that it does not communicate with any of the ejection grooves, and a second through hole arranged outside of another end side of the row of through holes so that it does not communicate with any of the ejection grooves.

Abstract: A liquid jet head includes a flow path member having a supply port through which liquid is supplied and a discharge port through which the liquid is discharged, and a cover plate having a liquid supply chamber that communicates with the supply port and a liquid discharge chamber that communicates with the discharge port. An actuator substrate has a plurality of parallel channels that extend between the liquid supply chamber and the liquid discharge chamber and the channels communicate with respective nozzles formed in a nozzle plate. The flow path member, cover plate, actuator substrate and nozzle plate constitute a laminated structure. A communication path is provided in one or both of the cover plate and flow path member for bypassing the liquid from the liquid supply chamber to the liquid discharge chamber so that air bubbles trapped in the liquid can be effectively discharged to the outside.
