Abstract: PROBLEM TO BE SOLVED: To provide an inkjet head capable of preventing a malfunction due to a heat from occurring by adequately radiating the heat.
SOLUTION: In a line head 35, ink is supplied to an ink channel 331 from an ink tank section 32 through an ink supply pipe 336 and a driving current is applied to a heating element 321 from a circuit on a printed board 360 through a terminal plate B 341 and a golden wire 342. In a nozzle applied with the current, a heating element 321 heats, a bubble is created on the surface of the heating element 321, and then ink having a volume roughly equal to that of the bubble is ejected from an ink ejection hole 311. While the heat by a heater chip 322 is accumulated a good deal by successive printing, as a fluid passage plate 330 made of an aluminum alloy is bonded to the heater chip 322, the heat generated on the heater chip 322 is efficiently radiated by the channel plate 330 so that it is possible to prevent a malfunction due to abnormal rising of the temperature from occurring.
