LIQUID JET HEAD, LIQUID JET DEVICE, AND METHOD FOR MANUFACTURING LIQUID JET HEAD

摘要

PROBLEM TO BE SOLVED: To provide a liquid jet head which can surely ensure conduction of wiring while preventing the damage of components, and to provide a liquid jet device equipped with the liquid jet head and a method for manufacturing a liquid jet head.SOLUTION: A recording head comprises: a head unit which includes a passage forming substrate 15 having a pressure chamber communicating with a nozzle and a piezoelectric element generating pressure fluctuation in the pressure chamber and jets ink from the nozzle by drive of the piezoelectric element; and a flexible cable 40 which includes a wiring terminal part 44 electrically connected to a piezoelectric element-side element terminal part 41 and supplies a driving signal to the piezoelectric element. The element terminal part 41 is laminated on the passage forming substrate 15. A bonding surface of either one of the element terminal part 41 and the wiring terminal part 44 is formed with an uneven part. Both terminal parts 41 and 44 are bonded to each other by a non-conductive adhesive 48.
