PROBLEM TO BE SOLVED: To provide an inkjet head that is free from a discharge error and is long-life by strengthening the fastening of the relay member and a vibrating plate. SOLUTION: The inkjet head is composed of an ink chamber communicating with an ink channel, a plurality of nozzles communicating with the ink chamber, a vibrating plate forming a part of the ink chamber and a piezoelectric vibrator provided in the position of the vibration plate opposite to the ink chamber. In the inkjet head varying the internal pressure of the ink chamber by expansion and contraction parallel with the polarization direction of the piezoelectric vibrator and discharging the ink from the nozzles, the vibrating plate is structured of a plurality of layers of an organic and inorganic substances, and the inorganic substance layer of the vibrating plate and a driving section are fastened together.
