Abstract: A liquid jet head is provided with an actuator substrate which is partitioned by elongated walls of piezoelectric body and has elongated grooves arrayed thereon so as to penetrate the substrate from an upper surface through a lower surface thereof, a cover plate which is attached to the substrate so as to cover upper surface openings of the grooves and has a liquid supply chamber which supplies liquid to the grooves, and a nozzle plate which is attached to the substrate so as to cover lower surface openings of the grooves and has nozzles communicating with the respective grooves. Drive electrodes are formed in strip form on side surfaces of the walls along the longitudinal direction thereof so as to be separated from the nozzle plate. The nozzle plate has a lower stiffness than the cover plate.

Abstract: Provided are a head chip, a liquid jet head, and a liquid jet recording apparatus, which can reduce the effect on image quality due to difference in volume of jetted liquid caused by pressure loss of the liquid during the liquid is in the process of circulating through a liquid flow path. The head chip includes first and second circulation paths (21a and 21b) extending along the longitudinal direction of the head chip so as to communicate to portions of a plurality of liquid jet channels, which are away from nozzle holes on an upstream side. The first and second circulation paths (21a and 21b) enable liquid to flow, the liquid being supplied to the plurality of liquid jet channels, and form liquid flows which are symmetrical with each other in the longitudinal direction of the head chip.
