To further improve the yield of an inkjet head. An inkjet head (1) is provided with: a head substrate (B) that comprises a nozzle (N) from which an ink is ejected downward, a pressure chamber (21) in which the ink that is to be ejected from the nozzle (N) is contained, and an actuator (60) which is provided so as to be in contact with the upper surface of the pressure chamber (21) and applies a pressure for ejecting the ink from the nozzle (N) to the ink within the pressure chamber (21); a wiring substrate (50) which is provided between the head substrate (B) and a supply part that supplies the ink to the pressure chamber (21), and which is provided with a conduction path (51) that communicates from the supply part to the pressure chamber (21); and a connection part (90) which has a bump (91) formed on the wiring substrate (50) and electrically connects a wiring line (52) of the wiring substrate (50) and the actuator (60) with each other. |
