Abstract (en)

[origin: EP3848204A1] Provided are an inkjet head and an inkjet recording device with which it is possible to effectively suppress image quality reduction caused by the heat of a drive substrate. The inkjet head comprises: an ink discharge unit in which the opening of a nozzle that discharges ink is provided to an ink discharge surface, the ink discharge unit having an operation element that performs an operation for discharging ink from the opening of the nozzle; a drive substrate in which a drive circuit is provided for driving the operation element; and an ink tank in which ink supplied to the ink discharge unit is stored, the ink tank being provided in an aspect in which a prescribed surface of the outer surface of the ink tank is provided along the drive substrate, and the heat of the drive substrate is propagated to the prescribed surface.
