PROBLEM TO BE SOLVED: To provide an inkjet head capable of maintaining a good and long-lasting print condition by minimizing ejection failure caused by air bubbles generated in supply passages. SOLUTION: An ink flow passage 53 is formed enabling for an ink liquid to flow in an arrangement direction of a plurality of ejection channels 13 at an end face as opposed to a manifold 17 of an actuator 14. Thus, even if air bubbles are generated within a supply passage 16, the liquid ink is favorably introduced into the ejection channel by means of the ink flow passage without being prevented by the air bubbles generated.
