Abstract:
An inkjet head includes: an ink tank plate that includes a nozzle to discharge a liquid; a drive circuit member connected to an electromechanical transducer to apply a voltage to the electromechanical transducer to generate a pressure in an ink tank to discharge a liquid from the nozzle; a liquid supply plate stacked approximately in parallel with the drive circuit member on the ink tank plate; and a sealing material that hermetically seals an electrical connection between the drive circuit member and the wiring member. The liquid supply plate is provided with a receptacle having a hole portion or a concave portion and a mount area surrounded by the receptacle. The drive circuit member is received in the mount area. The sealing material is filled inside the mount area after the liquid supply plate is bonded to the ink tank plate.
