Inkjet head and image forming apparatus having the same

An inkjet head comprising:

• an ink tank plate that includes
• a nozzle configured to discharge a liquid and
• an ink tank of which a portion is formed by a vibrating plate provided with an electromechanical transducer;
• a drive circuit member connected to the electromechanical transducer through a wiring member to apply a voltage to the electromechanical transducer so as to generate a pressure in the 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 to guide a liquid to the ink tank;
• and
• a sealing material that hermetically seals an electrical connection between at least the drive circuit member and the wiring member,
• wherein
• 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 formed on the ink tank plate,
• the drive circuit member is received in the mount area, and
• the sealing material is provided to be filled inside the mount area after the liquid supply plate is bonded to the ink tank plate.
