PURPOSE:To obtain an ink jet recording head which can easily be fabricated by providing arrays of ink cavities on the surface of a piezoelectric element plate, bonding a cover plate to the surface of the piezoelectric element plate and attaching a nozzle plate having a plurality of ink nozzles connected to each ink cavity continuously. CONSTITUTION:A plurality of ink nozzles 42 connected to each ink cavity continuously are provided on a nozzle plate 40, and the nozzle plate 40 is adhered to a piezoelectric element plate 10, 10, 10. Each ink nozzle 42 is formed on the nozzle plate 40, for instance, by etching process. Accordingly it is possible to provide ink nozzles 42 at an equal interval to an adjoining nozzle and also reduce manhours for fabrication of a piezoelectric plate by space which is otherwise occupied by the ink nozzle because of the formation of only the ink cavity 12 and an ink supply outlet 22 on the piezoelectric element plate 10.
