PROBLEM TO BE SOLVED: To flexibly set a jetting mode of various ink droplets.SOLUTION: An inkjet head 100 includes a laminated body, in which a spacer 20 and a piezoelectric body 10 are alternatively laminated. An ink channel 33 is determined by an ink channel formation cut groove 32 provided in the spacer 20 and the piezoelectric body 10. At least two electrodes 14 (14A, 14B) that oscillate the piezoelectric body 10 by application of a voltage pulse are provided in a direction along which an ink flow runs in the ink channel 33. While a voltage pulse is applied by the downstream side electrode 14A provided at the downstream side of the ink flow out of at least the two electrodes 14A, 14B, the voltage pulse is applied by the upstream side electrode 14B provided at the upstream side of the ink flow. |
