Zusammenfassung:	An inkjet head (1) includes a piezoelectric member (30), a plurality of electrodes (33), a protective lamination layer (34), and a nozzle plate (50). The piezoelectric member has a plurality of grooves (32). The electrodes are provided along surfaces of the grooves. The protective lamination layer covers the electrodes. The nozzle plate is on the piezoelectric member and has a plurality of ejection nozzles (N) that faces the plurality of grooves. The protective lamination layer includes an insulating layer (34A) and a first oxide layer (34B1) laminated on each other. The insulating layer contains an organic material. An oxygen content of the first oxide layer is greater than an oxygen content of the insulating layer.
