INKJET HEAD AND INKJET-TYPE RECORDING DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress generation of an abnormal vibration because of a rigidity decrease of a pressure chamber while a leak between nozzles is prevented at an inkjet head. SOLUTION: The inkjet head includes a nozzle plate 16, a head body 11 and an adhesive layer 12. A plurality of nozzles 15 from which ink is discharged are formed in the nozzle plate 16. The head body 11 has pressure chambers 23 which are formed communicating with the nozzles 15 and store the ink, and actuators 25 set for discharging the ink from the nozzles 15 by applying a pressure to the ink in the pressure chambers 23. The adhesive layer 12 set between the nozzle plate 16 and the head body 11 has an adhesive 12a for adhering the nozzle plate 16 and the head body 11 at positions corresponding to the pressure chambers 23 by an adhesion area of 20-80%.
