Head chip, liquid jet head and liquid jet recording device

Abstract

A head chip, a liquid jet head, and a liquid jet recording device capable of achieving the miniaturization while enhancing the reliability are provided. The head chip according to an embodiment of the disclosure includes an actuator plate having a plurality of ejection grooves arranged side by side in a first direction, a plurality of non-ejection grooves arranged side by side along the first direction, and individual electrodes respectively formed in the plurality of non-ejection grooves, a nozzle plate having a plurality of nozzle holes individually communicated with the plurality of ejection grooves, and a cover plate adapted to cover the actuator plate. The cover plate has interconnection connecting sections respectively disposed in end part areas along a second direction perpendicular to the first direction, and adapted to electrically connect a plurality of individual interconnections electrically connected to the individual electrodes to an interconnection board outside the head chip. The plurality of individual interconnections in the interconnection connecting section has a bend part extending in an oblique direction crossing the second direction so as to circumvent a predetermined obstacle. A connection area between the plurality of individual interconnections and the interconnection board in the interconnection connecting section is an area including the bend part.
