PROBLEM TO BE SOLVED: To provide an inkjet head capable of uniformizing heat distribution in an actuator. SOLUTION: The inkjet head 1 which is attached to a carriage of an inkjet recording device and to which ink is supplied to eject the ink from a nozzle hole is equipped with: a supporting body 11 having a plate-type base part 18 and a fixed part 19 which is provided at one end of the base part 18 and whose both ends in a longitudinal direction are fixed on the carriage; the actuator 12 having a plurality of groove-like ink chambers and attached to one surface of the base part 18 so as to generate driving force for ejecting the ink; and a nozzle plate formed in a plate shape having a plurality of nozzle holes and bonded integrally with the actuator 12. The base part 18 of the supporting body 11 is formed such that its surface to which the actuator 12 is attached is in non-contact with the actuator 12 in heat insulating areas R1 of predetermined length from both ends of the actuator 12 in a direction orthogonal to the ink chamber.
