PROBLEM TO BE SOLVED: To improve the reliability of an inkjet head 1 and the recording quality of a recorder A by devising a structure of the inkjet head 1 provided with a nozzle plate 5 where nozzles 51 are formed, a pressure chamber part 3 where pressure chambers 31 to be filled with ink are formed, an ink channel part 4 where ink channels 41 for supplying ink to pressure chambers 31 are formed, and piezoelectric actuators 21 for applying a pressure to pressure chambers 31 to discharge ink from nozzles 51, thereby preventing a flexible damper wall part 44 for sectioning the ink channel 41 and an air chamber 43 from being kept deflected. SOLUTION: A communication hole 6 is provided for letting the air chamber 43 communicate with the atmosphere. COPYRIGHT: (C)2003,JPO
