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.
