An ink jet head is provided with a passage unit, an actuator unit, and a conductive adhesion layer. The passage unit comprises a nozzle and a pressure chamber communicating with the nozzle. The actuator unit comprises a piezoelectric layer, a first electrode connected with a front surface of the piezoelectric layer, a second electrode connected with a back surface of the piezoelectric layer, and a first insulating layer located between the second electrode and the passage unit. The conductive adhesion layer adheres to both a front surface of the passage unit and a back surface of the actuator unit. The conductive adhesion layer is electrically connected with the second electrode.
