Abstract:
An inkjet head configured to eject inkjet ink includes a piezoelectric layer of a thin film and a diaphragm. An absolute value of a product of a piezoelectric constant d 31  of the piezoelectric layer and a Young's modulus of the piezoelectric layer is 10 [C/m 2 ] to 15 [C/m 2 ]. Even when the inkjet head ejects ink having a high viscosity, variation of driving voltage during ejection can be suppressed.

Claim (Index 7):
The inkjet head according to  claim 5 , wherein\n said donor ions include one or more kinds of ions selected from the group consisting of La, Nb, Ta, and W, said acceptor ions include one or more kinds of ions selected from the group consisting of Fe, Co, and Mn, and a difference in mol % ratio between said donor ions and said acceptor ions is 1 mol % or less.
