<p>An inkjet recording head, in which a part of the pressure generating chamber communicating with nozzle openings, from which ink droplets are ejected, are made up of a vibration plate and in which the ink droplets are ejected by the displacement of a piezoelectric layer formed on the surface of the vibration plate. The connecting portion connects a piezoelectric device (300) to a lead electrode (100) for applying a voltage to the piezoelectric device (300) which includes a lower electrode (60), a piezoelectric layer (70) and an upper electrode (80), all being formed in an area corresponding to a pressure generating chamber (12). The connecting portion is provided in an area which is other than the area opposing the pressure generating chamber and which faces a flow passage communicating with the pressure generating chamber (12). Narrow portions (13) having a width narrower than that of the pressure generating chamber (12) and communicating with one end of the pressure generating chamber (12) are formed by piercing a flow passage forming substrate (10) by etching. The inkjet recording head is mounted on the inkjet recorder to record character and image information on a recording medium such as paper by using ink.</p> |
