Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate dispersion in an impact location of ink, thereby improving yield even if voltage characteristics disperse due to a piezoelectric element. SOLUTION: A liquid jetting apparatus includes nozzles 40 arranged in an inkjet head 30 having a chamber 41 with a liquid nozzle hole 45 that fills an ink at its tip and the piezoelectric element 42 provided in the chamber 41, and configured to jet the ink from the hole 45 by varying a volume of the chamber 41 by applying voltage to the element 42; a velocity measuring section 62 that individually measures flying velocities of ink liquid droplets jetted from each nozzle 45 for every ink liquid droplet; and a voltage setting section 64 that individually varies and controls application voltages to the element 42 for every nozzle 40 based on the measured flying velocity for every ink liquid droplet.
