<P>PROBLEM TO BE SOLVED: To provide a liquid jet head of which the mounting reliability is enhanced by certainly connecting a lead electrode and drive wiring, a manufacturing method therefor and a liquid jet device. <P>SOLUTION: The liquid jet head is equipped with a flow channel forming substrate 10 to which a pressure generating chamber 12 communicating with a nozzle orifice for ejecting a liquid is formed, the piezoelectric element 300, which comprises a lower electrode 60, a piezoelectric layer 70 and an upper electrode 80, provided on one surface of the flow channel forming substrate 10 through a vibration plate, the seal substrate 30 bonded to the surface on the side of the piezoelectric element 300 of the flow channel forming substrate 10 to have a piezoelectric element holding part 31 for sealing the piezoelectric element 300 and the lead electrode 90 drawn out from at least one electrode 80 of the piezoelectric element 300 to the outside of the piezoelectric element holding part 31. In this liquid jet head, the flow channel forming substrate 10 and the seal substrate 30 are bonded by an adhesive 100 kneaded with a granular insulating material 101 to regulate the flow-out amount of the adhesive 100. <P>COPYRIGHT: (C)2004,JPO |
